Acute Cordyceps militaris supplementation and elevated resting oxygen uptake with faster reaction times: A randomized crossover trial.
Trial report in PloS one, 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
backgroundCordyceps militaris (CM) demonstrates neuroprotective properties in chronic preclinical models, but its acute effects on cognitive and physiological parameters during exhaustive exercise remain uncharacterized in humans. STUDY
designIn a randomized, double-blind, placebo-controlled crossover trial with a 7-day washout, 12 recreationally active young men (mean age 21.6 ± 2.9 years, VO₂max: 38.6 ± 5.5 mL·kg ⁻ ¹·min ⁻ ¹) ingested 1 g of standardized CM extract or a cornstarch placebo 30 minutes before a maximal cycling test to exhaustion. Cognitive performance (Stroop reaction time and accuracy) and physiological measures (oxygen uptake, blood glucose, blood pressure, and heart rate) were assessed pre-exercise and 3 minutes' post-exercise.
resultsStroop reaction time exhibited a significant main effect of Condition (F(1,11) = 5.45, p = 0.040) and Time (F(1,11) = 16.37, p = 0.002), with faster responses overall in the CM condition. Both conditions improved from pre- to post-exercise (placebo: -148.92 ms; CM: -104.67 ms). The Condition × Time interaction was non-significant (F(1,11) = 1.01, p = 0.337). No between-group difference was observed at pre-exercise (p = 0.167), but CM produced faster reaction times at post-exercise (963.92 ± 84.99 ms vs. 1034.33 ± 84.16 ms; p = 0.042, d = 0.88). Accuracy remained near-ceiling (>99%) with no condition differences. CM elevated resting VO₂ (0.37 vs. 0.24 L/min; p = 0.022) without altering peak exercise VO₂ (p = 0.490). No significant Condition effects or interactions were observed for blood glucose, blood pressure, or heart rate (all p > 0.05).
conclusionAcute CM supplementation improved post-exercise reaction time and elevated resting oxygen uptake, but did not alter the magnitude of exercise-induced changes in cognitive or physiological parameters. This suggests CM exerts an acute cognitive benefit independent of exercise modulation.
