Variations in mood states among Brazilian air force pilots: a crossover analysis between operational and aerobatic flight missions.
Article in Frontiers in physiology, 2025. 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
Background: Aerobatic flight maneuvers expose military pilots to a confluence of physiological and psychological stressors-including sustained G-forces, vestibular disorientation, and neuromuscular fatigue-that may acutely modulate emotional states and compromise cognitive performance. However, the differential psychometric impact of routine operational flights versus high-intensity air demonstrations remains poorly characterized. Purpose: To examine and compare mood state fluctuations elicited by distinct aerial mission profiles-operational maintenance (OM) flights and aerobatic demonstrations (AD)-within a specialized military pilot cohort. Methods: In this within-subject, crossover experimental design, nine elite male aviators (mean age: 32.1 ± 1.8 years) from the Brazilian Air Force Air Demonstration Squadron (EDA), each with >1,000 cumulative flight hours, were assessed across two mission contexts. Mood states were measured pre- and post-flight using the Brunel Mood Scale (BRUMS), which evaluates six psychological dimensions: tension, depression, anger, vigor, fatigue, and confusion. Paired comparisons were conducted using the Wilcoxon signed-rank test (α = 0.05). Results: OM flights were associated with a statistically significant increase in depression scores post-flight (p = 0.031), alongside a non-significant trend toward decreased tension (p = 0.098). Other subscales showed no statistically significant variation, though intra-individual variability was observed. Conclusion: Emotional reactivity among high-performance military pilots varies according to mission typology. Incorporating continuous affective monitoring and routine psychological assessments may bolster both operational readiness and mental health preservation in high-demand aviation environments.
