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: In basketball, identifying and developing potential athletes is crucial, and the Relative Age Effect (RAE) plays an important role in this process. However, could this effect interfere in the selection of elite players? Objective: The aim of the present study was to evaluate the RAE in Brazilian male and female basketball national teams in official competitions and to examine its association with the competition type, age category and collective performance. Methods: A total of 1,585 athletes were analyzed, including 703 males and 882 females. The mean age of the male athletes was 20.99 years old (±5.80), and their mean height was 196.72 cm (±9.36), while the female athletes had a mean age of 20.83 years old (±5.80) and a mean height of 179.00 cm (±6.44). The sample consisted of athletes who participated in world and continental competitions between 2002 and 2023, in the U15, U16, U17, U18, U19 and senior categories. The data were collected from the International Basketball Federation's website (https://www.fiba.basketball). Athletes' months of birth were categorized into quartiles and semesters, and the medalists and non-medalists team performance was analyzed, considering world and continental competitions besides youth vs. senior categories. To investigate the RAE across categories, the Chi-Square ( Results: The findings revealed a significant presence of the RAE ( Conclusion: The RAE is present at the elite level of Brazilian basketball over time, showing association only with the type of category.
