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.
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
introductionSleep quality can positively or negatively influences the physical performance of Brazilian Jiu-Jitsu fighters; however, the literature does not indicate whether the sleep quality of these fighters is good or poor.
objectiveCharacterization of the sleep quality of Brazilian Jiu-Jitsu (BJJ) fighters, stratifying by weight category and color belts. MATERIAL AND
methodsA descriptive study that featured with 175 BJJ fighters, the Pittsburgh Sleep Quality Index (PSQI) was applied to assess sleep quality. Mean, standard deviation and 95% confidence interval of mean were used to characterize the data.
resultsAll groups, regardless of weight category or color rank, were classified as poor sleepers (PSQI=5), which indicates a low sleep quality.
conclusionThe sleep of BJJ fighters is characterized as poor, which may indicate negative outcomes in technical and physical performance.
