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

The study investigated the impact of empty stadium matches and rule changes due to COVID-19 on the match performance in the Chinese Super League (CSL), including both technical and physical performance. Technical indicators considered were passing accuracy, number of passes, and number of challenges, while physical indicators included total distance, average speed, number of sprints, and sprint distance. Statistical significance was accepted at p < 0.001. The results showed that empty stadium matches led to a significant decrease in passing accuracy, while the number of passes and challenges increased. The changes in rules indicated a significant decline in players' total running distance, average speed, number of sprints, and sprint distance compared to pre-pandemic levels, although the average distance of high-speed runs increased. The pandemic had a more pronounced impact on players' physical performance. Coaches can use this information to adjust training plans for players during special periods to mitigate adverse effects on physical performance.
