Association between polygenic risk scores for four mental disorders and lifetime suicide attempt. Logistic regression was performed with each PRS as the independent variable and suicide attempters (N = 121) vs. nonattempters (N = 262) as the dependent variable. The x-axis illustrates the P-value thresholds used to filter the variants from each GWAS result. The y-axis illustrates Nagelkerke’s pseudo R². The P values for the associations are shown above each bar. *Asterisk indicates nominal significance (p < 0.05). PRS polygenic risk score, GWAS genome-wide association study
