Candy Crush over skipping rope? Real-time EEG-based anxiety index reduction via brief gaming interventions breaks in high-stress anesthesia residency shifts.
Article in BMC medical education, 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
backgroundMedical trainees in high-stress specialties like anesthesiology face elevated risks of anxiety and burnout, which may impair clinical performance. Traditional psychological assessments relying on questionnaires are limited by recall bias. This exploratory pilot study employed an EEG based Anxiety Index (ANXi) to evaluate anxiety levels among anesthesiology resident physicians in standardized training (ARPST) under varying shift duration.
methodsTwenty ARPSTs received ANXi monitoring during five shift periods: morning shift (P0), post-8-h (P1), post-24-h (P2), post-36-h (P3), and weekends (P4). Anxiety was assessed during clinical tasks (drug preparation, examination) and interventions (rest, music, TikTok browsing, Candy Crush gameplay, 200 rope skips).
resultsAll participants exhibited moderate-to-severe anxiety (ANXi > 45) during clinical tasks. While P3 showed the highest mean ANXi (58.1 vs. P0-P2: 49.8–55.7), inter-shift differences were non-significant (P > 0.05). Five minutes Candy Crush gameplay significantly reduced ANXi to sub-clinical levels (< 45) across all shifts (P < 0.001 vs. baseline). Conversely, 200 rope skips significantly increased anxiety (P < 0.001 vs. other interventions).
conclusionsThis pilot study suggests that five minutes Candy Crush offered immediate anxiety relief in high-stress clinical settings, whereas rope skipping increased anxiety. These preliminary findings still need further verification. CLINICAL TRIAL NUMBER: Not applicable. Data generated in this study are available upon reasonable request to the corresponding author.
