Chaos Caused by Different Cutoff Dates: Relative Age Effects and Redshirting in Collegiate Volleyball in the United States.

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
Relative Age Effects (RAEs) are a phenomenon in athletics related to an over-representation of individuals born closer to an arbitrary cutoff date. Such effects have been shown in many different countries, levels of play, and contexts, although they are yet to be studied in volleyball within the United States, which is the second most popular high school girls' sport and the fastest growing high school and college sport for males. Therefore, the purpose of this study was to examine RAEs in college volleyball. Publicly available data were collected from the websites of women's Division I program (
