Sex differences in the acute effect of caffeine on repeated sprint performance: A randomized controlled trial.
Trial report in European journal of sport science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 4 of them syntheses that pooled 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.
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
This study aimed to examine sex differences in acute caffeine intake on repeated sprint performance. Fifty-two resistance-trained individuals (age: 24.6 ± 4.5 years and sex (female/male): 26/26) participated in a randomized, triple-blind, cross-over, and placebo-controlled study. Participants ingested 3 mg/kg caffeine or placebo and, after 60 min, performed 4 Wingate tests (Wt), consisting of a 30 s all-out lower-body sprint against an individualized resisted load, with 90 s rest periods between sprints.
