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

introduction and hypothesisThis study aims to systematically estimate the global prevalence of overactive bladder (OAB), identify demographic and regional factors contributing to prevalence variations, and assess trends in prevalence over the past two decades.

methodsThis cross-sectional study was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guideline. From inception to April 2024, computerized searches for OAB prevalence-related literature were conducted on PubMed, Embase, Web of Science, and Cochrane. Studies of OAB prevalence in the general population were included. Two independent researchers conducted the screening, data extraction, and quality assessment of the included studies.

resultsA total of 53 studies, encompassing 610,438 participants, were ultimately included in the analysis. The meta-analysis determined the global prevalence of OAB to be 20% (95% CI 0.18-0.21). Over the past 20 years, there has been an increase in OAB prevalence, rising from 18.1% (95% CI 0.13-0.23) to 23.9% (95% CI 0.19-0.29). Among women, the prevalence of OAB was 21.9% (95% CI 0.20-0.24), indicating higher rates compared to men (OR = 16.1, 95% CI 0.15-0.18). The study also found higher prevalence rates among overweight and obese individuals (OR = 18.6, 95% CI 0.13-0.24) and those aged 60 years and above (OR = 28.3, 95% CI 0.24-0.33). Middle-income countries exhibited higher prevalence rates compared to high-income countries.

conclusionsThe study highlights higher risks of OAB among obese individuals, women, and the elderly. OAB prevalence has shown an increasing trend over the past 20 years.
