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: Perceived performance is associated with coaches' expert knowledge and athletes' sport emotion; however, the relationships among these variables have not been studied. This study aimed to investigate the structural relationships between the coaching knowledge of judo coaches and the sport emotion and perceived performance of Korean judo practitioners, or "judoka." Methods: Data from Results: Coaching knowledge significantly increased positive emotion ( Conclusion: High-quality coaching knowledge is associated with higher levels of athletes' positive emotion, reduced levels of negative emotion, and enhanced perceived performance. To optimize perceived performance, coaches should further develop their coaching expertise, while athletes should actively engage in emotion regulation strategies.
