Characteristics of the Study Population

Note.—Where applicable, values are means ± standard deviations.

^*Three repeat cases with a minimum repeat interval of 11.6 months were treated as separate entities.

^†SR vs no prior PCa group: P = .0303, AS vs no prior PCa group: P = .716, AS vs SR group: P = .497.

^‡To convert to Système International (SI) units in micrograms per liter, multiply by 1.0

^§SR vs AS group: P = .00319, SR vs no prior PCa group: P < .001, no prior PCa vs AS: P > .99.

^||SR vs no prior PCa: P = .0290, SR vs AS: P > .99, no prior PCa vs AS: (P = .0109).

^#To convert to SI units in micrograms per liter squared, multiply by 1.

^**Sample quality was inadequate for Gleason grading.
