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

objectiveEven though evidence showing increased prevalence of irritable bowel syndrome (IBS) among migraine patients exists, it has not been well-established and the magnitude of association varies substantially across the studies. This study aimed to comprehensively compare the prevalence of IBS among migraineurs versus nonmigraineurs using the systematic review and the meta-analysis technique.

methodsTwo authors independently conducted a literature search in MEDLINE, EMBASE and Google Scholar database up to April 2020. The eligible study must consist of two groups of participants, migraineurs and nonmigraineurs, and report the prevalence of IBS in both groups. Alternatively, an eligible study may report the odds ratio (OR) with a 95% confidence interval (CI) of the association between migraine and IBS. Point estimates and standard errors from each eligible study were combined together using the generic inverse variance method of DerSimonian and Laird.

resultsOf the 2531 articles identified from the three databases, 11 studies with a total of 28 336 migraineurs and 1 535 758 nonmigraineurs met the selection criteria and were included into the meta-analysis. The pooled analysis found that migraineurs had a significantly higher prevalence of IBS than nonmigraineurs with the pooled OR of 2.49 (95% CI, 2.22-2.78; I2, 42%). The funnel plot was asymmetric and suggested the presence of publication bias.

conclusionA significantly increased prevalence of IBS among patients with migraine was demonstrated in this study.
