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

This study investigates the relationship between referees' physical fitness, their in-game performance, and team dynamics in the Chinese Super League (CSL). The sample comprised 173 matches from the 2021 CSL season, involving 30 referees (mean age 41 years). The Pearson product-moment correlation coefficient was used to analyze the correlation between referees' physical fitness tests and their match performance indicator, as well as the referee's game performance and the home and away teams' game performance. Key findings include a significant positive correlation between referees' RSAVARIATION and the average speed during home possession (r =  0.16, p =  0.04). Additionally, RASBEST and RASAVERAGE were found to have small to moderate negative correlations with the referees' total distance, average speed, and high-intensity activities during games (r =  -0.20 to -0.34, p < 0.001). Furthermore, significant positive correlations were observed between referees' match performance metrics and the physical outputs of both home and away teams. These findings provide valuable insights for enhancing the understanding of factors influencing referee performance and can inform referee training, testing, and selection processes.
