Prevalence of irritable bowel syndrome in medical students: a systematic review and meta-analysis.
Synthesis in Frontiers in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The high prevalence of Irritable Bowel Syndrome (IBS) in university populations, especially among medical students, raises concerns about its impact on health and academic performance. Objective: To determine the prevalence of IBS in medical students through a systematic review (SR) and meta-analysis. Methodology: An exhaustive search was conducted in PubMed, Scopus, Web of Science, and Embase. A meta-analysis was performed to combine the overall prevalence, a sensitivity analysis to evaluate the robustness of the estimates, and meta-regressions to explore the influence of variables such as publication year and Rome criteria (III and IV). Results: Forty-three studies were included: 25 studies ( Conclusion: Irritable Bowel Syndrome is significantly prevalent among medical students, with substantial variability across studies driven by methodological factors (diagnostic criteria and sampling design) and population characteristics (sex and geographic region). High heterogeneity persisted across all subgroup analyses, indicating that local contextual factors are more influential than the broad categories examined. Probabilistic sampling protocols and standardized diagnostic criteria are recommended, as is the implementation of prevention and early management interventions in academic settings.
