  • aMultivariable models were adjusted for age at RP, PSA, RP grade group <4 or ≥4, and pathologic stage. RP grade group was analyzed as dichotomous variable due to low number of metastatic events per grade group.

  • bNo metastatic events were observed for CHD1 genetic alterations, hence HR and P values were not calculated.
