Relative Age Effect Is Widespread among Most Successful Youth, but Not in Senior Olympic Weightlifters.
Article in Journal of human kinetics, 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
The aim of the study was to investigate the prevalence of the relative age effect (RAE) among elite Olympic weightlifters in different age groups. The prevalence of RAE was studied among top 10 participants from the World Weightlifting championships for youth, junior and senior age groups and from the Olympic Games from 2009 to 2022. Birth dates of 3886 athletes were analyzed and further divided into four groups according to the birth quartile. Weight categories were grouped as lightweight, middleweight and heavyweight. The effect was found among lightweight and heavyweight girls, boys of all weight groups, lightweight and middleweight junior females and juniors of all weight groups. In the senior group, RAE was only present among heavyweight males. Differences in the prevalence of RAE between male and female weightlifters were statistically significant (p = 0.009). Differences in effect between youth and junior age groups were not significant (p = 0.24). The findings of this study demonstrate that RAE tends to be widespread among the best weightlifters of both sexes in youth and junior age groups, but disappears in most weight groups at the elite senior level.
