Healthcare decisions should be based on evidence generally provided by randomized controlled trials (RCTs) comparing two or more interventions for a condition that affects the target population.

When more than one study is available, meta-analysis can be used to combine several intervention effects and obtain an overall estimate of that effect size in the target population. However, for most clinical conditions, there are more than two effective interventions. In such cases, it is not possible to perform multiple pairwise meta-analysis. Additionally, direct clinical trials may not be designed and implemented for all interventions.

Network meta-analysis (NMA) is a method for comparing multiple interventions simultaneously in a single study using a combination of direct and indirect evidence in a network of RCTs the results of which enable us to rank all the interventions in a coherent way.

The present study was designed to provide a basic explanation of the benefits of producing a direct and indirect evidence-based network, reviewing key assumptions in NMA, and explaining the stages of performing NMA. In addition, by using an example to evaluate the cardiac toxicity of different interventions to treat HER-2 positive breast cancer, the implementation and production steps of the meta-analysis network were presented.

Sexual dysfunction is the most common psychiatric disorder in the general population. The high cost and side effects of present treatments have prompted researchers to search for other therapeutic options. The aim of this study was to evaluate and summarize the results of trials on the effects of roses on sexual dysfunction through a systematic review.

In this study, EBSCO, Web of Science, Scopus, SID, Magiran and Irandoc databases and PubMed and Google scholar search engines were searched with no time limits using the keywords Rose, Rosa damascena, Rosaceae, Sexual function, Sexual dysfunction, Sexuality and Sexual. Searching, screening, selection and quality appraisal of the articles were done by two researchers independently.

Out of 251 articles found in the primary search, six articles and one thesis have inclusion criteria, (178 women and 55 males). Most of studies have high quality. Only one study in the field of performance and a study in the area of selection had a high-risk bias. According to the results of included studies, roses have improved the symptoms of sexual dysfunction in depressed patients, female and male patients under methadone maintenance therapy, menopausal women, and normal reproductive age women.

The results indicate the effectiveness of roses on sexual dysfunction, particularly those with underlying disorders. Therefore, given the acceptance of the use of complementary therapies, it can be used as an affordable and inexpensive method along with other available treatments.

Gait is functionally highly relevant aspects of motor performance. This aim of this study was to determine biomechanical characteristics gait in intellectual disabilities during 1995-2017. In this systematic review, all quantitative and qualitative studies that related to gait and balance characteristics of intellectual disabilities were retrieved from Persian databases (Magiran, SID, Google scholar) and all full text articles with keywords intellectual disability, gait were retrieved from English databases (PubMed, EBSCO, Science Direct, ProQuest). Then, 16 papers selected from 35 papers. Also, “Data Extraction Form" which developed based on research aim, was used for data collection. 14 of 16 articles (87.5%) were quantitative and 2 articles (12.5%) were qualitative. The results showed that intellectual disabilities were related to gait disorders, especially step length, stride length, shorter step width and lower velocity. It also has kinetic and kinematic disorders, including reduction of the ankle production power in the push-off phase, increased hip and knee flexion at stance phase, knee limitation and plantar ankle flexion at the heel contact and joint stiffness during the gait. Gait disorders in intellectual disability is a serious problem. Preventive measures are recommended to correct gait disorders and reduce complications.

The use of electronic health literacy has increased in recent years. Therefore, it is important to know the factors associated with its application in order to maintain and improve the quality of life. The present study aimed to determine the factors related to the use of electronic health literacy during 2006-2017. In this systematic review study, all the full-text articles were obtained through the Google Scholar, Pub-med, Science Direct and Springer databases. Key words include literacy, health, and e health literacy. In order to collect data, the “Data Extraction Form" was developed based on the purpose of the research. The result of this search was to achieve 39 articles, of which 32 were excluded due to lack of entry criteria and finally 7 studies were submitted to the study. 9 other articles that specifically looked at the factors related to electronic health literacy were entered into the study through manual search. A total of 16 articles in English were considered in this review. Five of 16 articles (31.25%) were mixed methods research, two (12.5%) were descriptive studies, two (12.5%) were descriptive correlational studies, three (18.75%) were reviewed studies. In addition, a semi-experimental study, an experimental study, a qualitative study, a descriptive survey study, (6. 25%) were other methods of studies. The dimensions of search skills, application and assessment, mastery of computer literacy, academic literacy, traditional health literacy, media literacy, information literacy, communication literacy and secure access to electronic health information are among the factors associated with the use of electronic health literacy. It is suggested that the related factors be used to improve the electronic health literacy skills.

There are many research have been done so far about the effect of exercise training on diabetic type 2 related risk factors. But in this regard there is no study performed in Iran. So, the aim of the present study was to investigate the effect of endurance exercise training on some diabetic type 2 dependent variables in the form of systematic review and meta-analysis of studies that were performed in Iran.
In this research PubMed, Embase, Cochran, Scopus, ISI, Google Scholar, Science direct, Sid and Magiran databases were searched for Persian sources. Data analysis were done using STATA software version 12.0.
Generally, 242 articles were founded in primary search, which 24 articles were included in this research. Finally research were evaluated 592 Iranian's peoples which 294 peoples as a control group (96 male and 198 women) and 298 peoples as a training group (97 male and 201 women).The results indicate that there were significant association between endurance exercise and blood glucose levels (P=0.0001,-1.016,-0.656;95%CI), insulin (P=0.0001,-1.042,-0.682;95%CI), insulin resistance (P=0.0001;-0.563,-0.217;95%CI).
Generally, this systematic review and meta-analysis study was demonstrated endurance exercise could be related with decrease diabetes type 2 related risk factors. So, it is recommended that sport and medicine experts use endurance exercise as a non- pharmacological intervention for treatment of diabetes type 2 patients.

Instrumental assessments can provide numerical values in nasality assessment. One of these instruments is the nasometer (Kay Elemetrics¡ Lincoln Park¡ NJ¡ USA). The nasometer measures the oral and nasal acoustic energy during speech and the resultant signal is expressed as a nasalance score. The aim of the current review was to study the impact of age and speech stimulus on nasalance score through a systematic review of studies on nasalance.
The ASHA publication¡ PubMed¡ ScienceDirect¡ Google Scholar¡ Cochrane¡ Wiley¡ ProQuest¡ IranDoc¡ and SID databases were searched using the keywords “nasalance”¡ “nasometer”¡ “normative nasalance score”¡ and “instrumental assessment of resonance disorders” for related articles published between 1990 and 2016.
Based on the inclusion and exclusion criteria¡ 38 of the 67 published documents were selected to be reviewed. The review showed that different studies had obtained different results regarding the effect of age and speech stimulus on nasalance scores.
As¡ in addition to age and speech stimulus¡ many factors (like language¡ accent¡ and gender) affect nasalance scores¡ a meta-analysis study seems to be necessary on this topic.

Cancellation of surgical procedures is one of the biggest challenges in hospitals throughout the world and it is important as it increases patient's stress, expenses and wastage of time, and prolongs the duration of hospitalization of patients. The aim of this study was to review literature related to reasons of surgery cancellation in Iran.
This systematic review was conducted from March to Sep. 2014. The keywords including cancellation, delay, postpone, cancelled surgery, surgery operation and Iran were searched in international search engines including Pubmed, Scopus, ProQust and Google scholar and Persian indexing websites of SID, Magiran and Iranmedex. All articles related to cancelled operations in Iran, written in English or Persian (from Jan 1, 2004 until Sep 31, 2014) were collected. Then, those articles which contained any of the selected keywords in their titles or abstracts were compiled, and others were excluded. At last, a check list including title of article, time and location of study, sample size and location and cancellation cause was designed for final assessment.
A total of 646 records were found in 7 selected databases of which 13 articles met the criteria for inclusion in this study. The main cases of surgery cancellation were related to operating room and hospital, anesthesia, patient's non-clinical problems, the surgeon and clinical problems.
Adoption of strategies for on-time initiation of surgical procedures, identification of patient's underlying problems and the appropriate process of hospital admission can be effective in reducing the rate of cancelled operations.

Along with science and technology advancement, philosophy, content and educational methods are transforming. Modern approaches such as constructivism have replaced traditional approaches and the assumption of knowledge transfer from teachers to learners. One of these approaches is concept map. The purpose of this paper was to examine the application of concept maps in education and learning.
In this review study, all of Persian studies published on the subject of concept map from 2001-15 were searched and reviewed through three electronic Persian databases (Magiran, SID and Iranmedex). Selected publications were analyzed by means of content analysis.
Sixty-one papers were excluded from a total of 98 publications based on inclusion criteria. Findings showed that 94.6 percent of the papers had assessed with the application of concept map in education, while the remainder dealt with its application in learning evaluation. The subject of 54 percent of the papers was in the field of health with 43.2 percent in the nursing education field.
Concept map is introduced in education as a learning-teaching strategy which promotes deep and meaningful learning. In the field of health in general and nursing in particular, concept map has led to deep and meaningful learning, improved clinical decisions, enhanced critical thinking and problem solving skills, increased student interactions, enhanced self-efficacy and cognitive strategies. It also has improved creativity, patient training, leadership style, care management and has facilitated the analysis of disease information in complicated clinical environments.

One of the perennial challenges associated with coding diagnoses and treatment, quality data encryption is. Accuracy, reliability, completeness timed and all the components are coding quality. The aim of this study was to evaluate studies on the quality of diagnostic coding and medical care and its determinants in Iran, respectively.
This study is a systematic review, in which all articles published on the topic in the lower period 1380 to the end of March 1394 (March 2001 to March 2015) were studied. Internet search to find articles in the internal data base Magiran, BarakatKnowladege Network System, Irandoc, SID and external databases, Google scholar, Science Direct and PubMed and was Persian and English keywords. 200 articles published in Farsi and English were retrieved and finally 14 articles were identified and evaluated.
Four paper specifically examines the components of quality of coding, six paper examines the factors affecting coding quality, and the four paper also common for both components and factorsaffecting coding quality were examined. Component coding quality, most studies (seven cases) were examined coding accuracy. The factors affecting coding quality, most studies (five cases) to investigate the role of documentation and diagnosis recording among, respectively.
The results of the study showed that among the components of quality timeliness of coding properties is not desirable. Findings of the study on factors affecting coding quality is the importance of observing principles of documentation on coding quality.

In this study, the prevalence of Echinococcus granulosus was surveyed by meta-analysis and systematic review. Using main keywords of Echinococcus granulosus, dog and carnivores, we searched standard sites such as Google scholar, SID, Pubmed, Iranmedex, Irandoc, Science direct and magiran. Fifteen reliable articles were reviewed and analyzed by STATA software, Ver 11. From obtained articles, the number of 2271 dogs, 167 jackals and 174 foxes have been investigated by Iranian researchers. The infection rate of E.granulosus was reported 27.4% (95% CI, 20.9-33.9) in this study in that the highest from north and north west of Iran with prevalence of 33.3 %(CI:22.1-44.4), the lowest by 21.9 %(CI:12.5-31.3) from west and south west of Iran and the average from the central region of Iran (26.9%; CI:12.8-41). Among cities the highest (64%) and the lowest (3.3%) infection rate were reported in Garmsar city (2010) and Sistan and Balochestan province (1997). Given that the overall prevalence of E.granulosus in Iran is high, Control and prevention measures including destruction of stray dogs and treatment of owner dogs seems to be necessary.
