Identification of a reverse crossover point during moderate-intensity exercise (>6 h; 69% VO
Article in Frontiers in nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Re-analysis results (Left) and takeaway messages (Right) are summarized above. RCOP, reverse crossover point. Figure created with Biorender.com.Reverse Crossover Point (RCOP) analysis showing a man on an exercise bike and running, indicating training intensity. A graph illustrates substrate oxidation levels over time, with fat oxidation surpassing carbohydrate oxidation. Key takeaways: Fat oxidation increased significantly despite carbohydrate intake, suggesting additional carbohydrate sources and reliance on lipids for energy.
