Effects of Different Doses of Caffeine on Endurance Exercise Performance in the Heat.
Article in Life (Basel, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis 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 investigated the effects of different doses of caffeine (3 mg/kg BW and 6 mg/kg BW) on endurance exercise performance in the heat. Seventeen participants completed four randomized, double-blind trials: one in a normal environment (24.6 ± 1.2 °C) and three in a hot environment (33.2 ± 1.4 °C), with placebo, 3 mg/kg BW, and 6 mg/kg BW caffeine interventions. Endurance exercise time, cardiorespiratory function, and subjective fatigue perception were measured during incremental cycling tests. The results showed that high temperatures significantly reduced endurance exercise performance in the placebo (
