Multivariate analyses was conducted with incorporation of the covariates number of cores, age, prostate volume, PSA, history of previous biopsy, active surveillance status, and ISUP category. Besides for the covariate number of cores, only significant results are shown.
OR odds ratio, CI confidence interval.
Asterisks indicate statistical significance: *P < 0.05; **P < 0.01.
