Abbreviations: IR, incidence rate; PCa, prostate cancer.

  • aAdjustment was made for the following covariates (values at baseline): birth-year, age, height, body mass index, type 2 diabetes, smoking, family history of prostate cancer, education, residency in early life, and regular health check-ups.

    Data on RPA were incomplete for 292 men, leaving 8,784 men in the analytic cohort.

    Number of individuals in multiadjusted analysis was 3% to 4% lower than in the age-adjusted analysis (due to missing values for covariates).
