Sample sizes represented by the height of rectangles and prevalence of significant prostate cancer represented by the width of rectangles for the 11 PBCG cohorts used in the study. The cohorts have been numbered according to their rank of clinically significant prostate cancer prevalence. The 3rd cohort in black outline was withheld to serve as an external validation cohort with the remaining 10 cohorts used for training prediction models
