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.

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.

Abstract

objectiveThis study was designed to compare the severity of gastrointestinal (GI) side effects in Type 2 diabetes mellitus (DM) patients receiving tablet or capsule forms of metformin.

methodsIn this prospective interventional study, patients were evaluated from June to November 2016 at DM clinics affiliated to Isfahan University of Medical Sciences, Isfahan, Iran. Adult patients with Type 2 DM who were eligible for inclusion criteria switched from metformin tablet to metformin capsule. Hemoglobin A1c (HbA1c), GI side effects, and patient satisfaction based on visual analog scale (VAS) were assessed during a 6-week follow-up of receiving metformin capsule.

findingsOne hundred and three patients were evaluated, and 75 patients participated in this study. At the baseline, 40 patients (53.3%) had GI side effects due to metformin tablet which was reduced to 16 patients (21.3%) after switching to metformin capsule (

conclusionSwitching to metformin capsule may result in less GI side effects, with no further side effect complications.
