Discrimination for significant prostate cancer comparing logistic regression models using total PSA, PSA density, and the Stockholm3 test

	ISUP grade group ≥2	ISUP grade group ≥3
	AUC (95% CI)	AUC (95% CI)
Total PSA	0.61 (0.56–0.65)	0.65 (0.58–0.72)
PSA density	0.70 (0.66–0.74)	0.72 (0.65–0.78)
Stockholm 3	0.77 (0.73–0.80)	0.77 (0.71–0.83)

AUC = area under the receiver operating characteristic curve; CI = confidence interval; ISUP = International Society of Urological Pathology; PSA = prostate-specific antigen.
