The Influence of Short-Term, Severe Low Energy Availability With Varying Protein Content on Substrate Metabolism, High-Intensity Exercise Performance and Subjective Responses in Young Adults.
Trial report in European journal of sport science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Low energy availability (LEA) may impact multiple biological processes, but the extent to which it affects exercise performance, and whether macronutrient composition modulates this, remains unclear. This randomised crossover trial investigated the influence of three dietary conditions with varying energy and protein availabilities on substrate metabolism, high-intensity exercise performance and subjective responses in healthy active females (9) and males (10). Each condition lasted 5 days. On Day 1, resting metabolic rate, substrate metabolism during a 45-min fixed-load cycling test at 65% of the peak power output achieved during an aerobic capacity test, and Wingate performance were assessed. Participants were then provided with all foods to be consumed over the next 4 days, with the following caloric and protein content: adequate energy availability (AEA: 45 kcal·kgFFM
