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
IntroductionEndurance and ultra-endurance running impose substantial physical and psychological demands, leading athletes to experience intense emotional states before, during, and after competitions. Accordingly, there is a paucity of evidence comparing mood profiles between endurance and ultra-endurance runners competing in trail and mountain events.ObjectiveThe aim of this study was to characterize the mood profile of endurance and ultra-endurance runners participating in La Misión Brasil 2024 and to analyze its relationship with sleep quality.MethodsThis prospective cross-sectional study included 193 runners, divided into an endurance group (n = 118; men = 75; women = 43) and an ultra-endurance group (n = 75; men = 60; women = 15), who participated in the same competition according to the proposed distances. La Misión Brasil is a trail running event with race distances ranging from 25 to 80 km and substantial elevation gain. One week prior to the competition, participants completed questionnaires assessing mood state, anxiety, psychological health, and sleep quality. Comparisons between groups (endurance group vs. ultra-endurance group) and sexes were performed using independent
