Table 3.

Different models used for discriminating between PCa and BB patients using the AIC.

Model	AIC	LR-test P-value 1^st vs. others
Age + log(tPSA) + log(fPSA) + log(tPSA)*log(fPSA)	629.61	—
Age + log(tPSA) + log(fPSA)	635.88	0.004
Age + CPR + FPR	704.86	<0.001
Age + log(PSA-α₁ACT) + log(fPSA) + log(tPSA) + log(PSA-α₂M)	637.12	<0.001
Age + log(PSA-α₁ACT) + log(fPSA) + log(tPSA) + CPR + FPR + log(PSA-α₂M)	631.34	0.91

The model with the lower AIC value was selected as the best model. *Indicates an interaction relationship.
