The violin plots of the median ancestry standardized PRS distributions between cases and controls in pediatric Training (A), Validation 1 (B), and Validation 2 cohorts. In the boxplot insert, the dot within each box indicates the median score. In the Training cohort (A), the median standardized score of cases was 60% vs 47% in controls (p<0.0001). In the Validation 1 cohort (B), the median standardized score of cases was 58% vs 48% in controls (p<0.0001). In the Validation 2 cohort (C), 67% in cases versus 49% in controls (p<0.0001). The top and bottom of the boxes indicate the interquartile range (75th and 25th percentiles), respectively.
