A single dose of cajuína does not improve leukocyte count, lipid peroxidation, and physical performance in runners: a randomized, crossover, double‑blind, placebo study.
Trial report in European journal of 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
purposeTo investigate the effects of a single dose of cajuína juice physical performance, leukocyte counts, and oxidative stress markers following a 10-km time trial in male runners.
methodsA total of nine recreationally trained male runners (32 ± 9.2 years; 70.9 ± 8.1 kg, 1.71 ± 0.06 m, 3.9 ± 1.9 training sessions per week) were randomly assigned to receive either cajuína juice (containing approximately one gram of vitamin C) or a placebo (a similar drink containing 0 mg of vitamin C) two hours before exercise, with a one-week washout period between interventions. Blood samples were collected immediately before ingestion and post-exercise. Leukocyte counts, as well as malondialdehyde (MDA), uric acid, and albumin concentrations, were analyzed from the samples.
resultsPhysical performance was not affected by cajuína intake (p > 0.05). Although a time effect (p = 0.01) was observed for MDA concentrations, no condition (p = 0.47) or interaction effects (p = 0.84) were revealed. Additionally, there were no effects of condition, time, and interaction for albumin (p = 0.83, p = 0.37, and p = 0.16, respectively) and uric acid (p = 0.64, p = 0.19, and p = 0.55, respectively) concentrations. No significant or positive changes in leukocyte counts were observed (p > 0.05).
conclusionThe single-dose intake of cajuína (Anacardium occidentale L.) does not improve leukocyte count, lipid peroxidation, or physical performance in recreationally trained male runners subjected to a 10-km time trial.
