The intervention group had significantly lower state anxiety levels (54.8 ± 13.40, mean ± standard deviation) compared to the control group (63.56 ± 12.20, p = 0.009; Cohen's d = 0.692, 95% CI [0.154, 1.19]), indicating a moderate effect size. Student’s t test. STAI: state-trait anxiety inventory.

Correlation between OSCE scores and state anxiety.
Correlation between Objective Structured Clinical Examination (OSCE) scores and State-Trait Anxiety Inventory (STAI) state anxiety scores in medical students (n = 62). A weak, non-significant negative correlation was found between OSCE performance and state anxiety (rs = −0.18; p = 0.17).
Fig 4.
Objective Structured Clinical Examination (OSCE) scores for the Intervention and Control groups. The intervention group achieved significantly higher OSCE scores (median = 8.60, IQR = 0.80) compared to the control group (median = 8.30, IQR = 0.90; p = 0.055, Mann-Whitney U test), with a small effect size (Rosenthal’s r = 0.277; 95% CI [−0.000019, 0.600]). IQR = interquartile range. CI = confidence interval.
