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

purposeCombat sports, such as judo, are weight categorized. Weight control was established to promote fair disputes among individuals. However, combat sports athletes adopt rapid weight loss (RWL) to obtain an advantage over smaller and lighter opponents. This scoping review article presents the prevalence, magnitude, and methods of RWL and its effects on physical and competitive performance, health risks, and psychological effects. Specific recommendations for attenuating the effects of RWL are also presented.

methodsStudies were retrieved from Web of Science, PubMed, and Scopus databases. Four hundred and forty-six articles were identified, of which fifty-three were considered eligible for this review.

resultsThe results showed that the prevalence of RWL was between 40% and 92.9% and that athletes reduced their body mass by approximately 5%. Although the literature suggests that RWL impairs the performance and psychological well-being of athletes, these results were obtained when recovery time was not provided.

conclusionNo negative effects on performance were observed when the recovery time was >4 h. However, health risks due to RWL practices should be considered, and RWL should be avoided.
