1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

BACKGROUND Gastroesophageal reflux disease is a common, chronic disease worldwide. The weekly prevalence of reflux in developed countriesis 10% to 48%. It has previously been reported as 5% in Asian countries, but new reports show a higher level in both Asian and Arab countries. In Iran, reflux has increased over the last two decades. There are few studies concerning the prevalence of refluxin Iran. This study aims to review reports about the prevalence of reflux in Iran, as it may be different in various parts of the country. By evaluation of the existing articles, this study will reach a general conclusion about the reflux prevalence in Iran. METHODS This was a qualitative, systematic review that estimated the prevalence rate of reflux in Iran. In August 2010, we reviewed all electronic database published studies that concerned the epidemiology of reflux prevalence in Iran by searching PubMed, Scientific Information Database (SID), Iran Medex, and Magiran. RESULTS In our search, using specified key words and selection criteria, 15 articles fulfilled the inclusion criteria and were included in the study. CONCLUSION According to the results, the data related to the estimated prevalencein Iran have a wide range. The weekly prevalence rate of 21.2% in the Tehran study is the best estimate for reflux in Iran. It seems that reflux is more common in Iran when compared to other Asian countries, and similar to reflux in Western countries. Due to the absence of comprehensive studies in Iran, we recommend that researchers conduct accurate, comprehensive, multi-dimensional studies in order to estimate reflux prevalence and its burden inIran.
