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/Aims: Symptoms of irritable bowel syndrome (IBS), a common gut-brain interaction disorder, deteriorate patients' quality of life and increase medical needs; therefore, IBS represents a significant global burden. The estimated global prevalence is approximately 10%; however, accumulated evidence shows international heterogeneity. In this study, we have described and compared the prevalence of IBS in 3 East Asian countries: Japan (Tokyo and Fukuoka), China (Beijing), and South Korea (Seoul). Methods: We conducted an internet-based cross-sectional survey of the urban population aged > 20 years in the abovementioned countries. We recruited equal numbers of age- (20s-60s) and sex-matched participants (3910 residents). IBS was diagnosed according to the Rome III criteria, and the subtypes were analyzed. Results: The overall prevalence of IBS with 95% CI was 12.6% (11.6-13.7); the prevalence was significantly different across Japan, China, and South Korea (14.9% [13.4-16.5], 5.5% [4.3-7.1], and 15.6% [13.3-18.3], respectively) ( Conclusions: The overall prevalence of IBS in the 3 countries was slightly higher than the global prevalence, and it was significantly lower in China than in Japan and South Korea. IBS prevalence was the highest and lowest among individuals in their 40s and 60s, respectively. Male individuals had a higher prevalence of IBS with diarrhea. Further studies are needed to elucidate the factors associated with this regional heterogeneity.
