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/

aimsVarious foods trigger and/or worsen the symptoms of irritable bowel syndrome (IBS). However, Korean food-related gastrointestinal (GI) symptoms in IBS patients have not yet been investigated. This study aims to evaluate the prevalence of self-reported food intolerance in Korean IBS patients and determine the Korean food items and food groups perceived by patients to worsen their GI symptoms.

methodsWe recruited 393 study subjects, comprising 101 IBS patients, 167 symptomatic non-IBS subjects, and 125 control subjects. All participants completed a questionnaire to identify the most problematic foods and assess the occurrence of GI symptoms caused by 119 Korean food items. They also completed the validated Rome III questionnaire for IBS.

resultsThe prevalence of self-reported food intolerance in Korean IBS patients was 79.2%, which was significantly higher than that in control subjects (44.8%,

conclusionsA large proportion of Korean IBS patients complained of intolerance to certain food items, with high-fat and high-FODMAP foods being the main triggers. This study provides a basis for planning food intervention studies for Korean IBS patients.
