aFor each of the respective population groups, p < 0.05 when comparing the median age between cases and controls.
bFor each of the respective population groups, p < 0.05 when comparing the median PSA between cases and controls.
‡Gleason score, tumour stage, and/or metastases information were missing from the medical records of some of the clinically confirmed prostate cancer cases. Therefore, the numbers and percentages shown are for the available information and not that of the total number of cases included in the study for each population group.
