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 Currently, it has been demonstrated that gastroesophageal reflux disease (GERD) is one of the most important disorders of the digestive system and the commixture of regular diet has a significant influence on its incidence, symptoms, and prognosis. The purpose of this study was to evaluate the effect of zinc supplementation, in combination with PPIs(Proton pump inhibitors), on the improvement of GERD symptoms. METHODS In a randomized double blind clinical trial, patients with reflux symptoms, who had obtained Reflux Disease Questionnaire (RDQ) score more than 8, were included and all the demographic features were recorded. Then, using upper gastrointestinal (GI) endoscopy, all the patients were divided into two groups as having non-erosive reflux disorder (NERD),or erosive reflux disorder (ERD). At the next step, based on random block statistical method, we divided the two groups into two subgroups; the drug subgroup [treated with PPIs (40 mg pantoprazole/daily), changing life style, and 220 mgzinc capsules daily] and the placebo subgroup [treated with PPIs, changing life style, and placebo]. After 3 months, we analyzed all data and the RDQ questionnaire was filled out for each patient. This project has been registered in Iranian Registry of Clinical Trials (IRCT) and all data were analyzed using SPSS software version 2. RESULTS A total of 140 patients (81 women and 59 men) with mean age of 42.78±11.5 years were included with 70 patients in each group. The most frequent presentations were heart burn (45.7%), and acid regurgitation (39.3%). The RDQ scores decreased after intervention in both drug (p<0.001) and placebo groups (p<0.001), which were statistically significant. But the difference of RDQ scores between the drug group and placebo group was not statistically significant (p=0.086). CONCLUSION Zinc supplementation cannot improve the severity of GERD.
