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

backgroundExercise-induced bronchoconstriction (EIB) is a prevalent respiratory condition among summer sport elite athletes, yet epidemiological data from Asian populations remain scarce. The objective of this study was to investigate the prevalence, sport-specific patterns, and physiological characteristics of EIB in Chinese summer sport elite athletes.

methodsA cross-sectional study of 500 summer sport elite athletes across 17 sports was conducted. Participants underwent standardized exercise challenge testing, spirometry, and serum biomarker assessments (eosinophils, interleukin-5 (IL-5), interleukin-8 (IL-8), Clara Cell protein 16 (CC16), immunoglobulin E (IgE), and uric acid (UA)).

resultsEIB prevalence was 27.6% (138/500), with significant variation across sports: highest in swimming (51.52%) and lowest in wrestling (6.45%). Female athletes were more prevalent than males (31.1% vs. 23.7%, p = 0.030). Outdoor sports demonstrated higher rates than indoor disciplines (37.4% vs. 19.4%, p = 0.002). EIB-positive athletes showed pronounced post-exercise declines in forced expiratory volume in 1 s (FEV

conclusionThis is the first large-scale study of Chinese athletes to reveal EIB prevalence exceeding global averages. Distinct risk profiles emerge, associated with gender, athletic level, sport type, and environmental factors. The findings outline the need for targeted screening programs and biomarker-guided management to mitigate respiratory health risks in athletic populations.
