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

backgroundThe aim of this study was to investigate the time course of cardiac arrhythmias following a bout of high-volume exercise and to identify factors associated with abnormal cardiac arrhythmia.

methodsThirty-four recreational cyclists with 12 (interquartile range, 7-20) years of riding experience were recruited for this repeated-measure cohort study. Participants cycled for up to 6 hours at ≈80% heart rate reserve. Cardiac arrhythmias were recorded using a 5-lead Holter monitor for 4 days before exercise, the day of exercise, and 4 days after exercise. Arrhythmias were quantified as totals, abnormal arrhythmias (arrhythmias meeting international consensus criteria for cardiac arrhythmias requiring further investigation), and relative risk.

resultsSixty-eight percent of participants displayed abnormal cardiac arrhythmias. No between-day differences in the number of arrhythmias were found (

conclusionsHigh-volume cycling increased the likelihood of abnormal ventricular arrhythmia on the day of exercise. Extended monitoring revealed a high prevalence of abnormal cardiac arrhythmias among recreational cyclists. Current screening practices in many countries are typically limited to elite athletes, meaning recreationally active people are not routinely assessed for exercise-induced arrhythmias. Our findings suggest that some individuals in this group may have clinically relevant arrhythmias that would otherwise go undetected without targeted evaluation.
