Predictive value of different parameters in verification set.

	N	PCa patients	Low-risk	Intermediate-risk	High-risk
		37/37	9/37	12/37	16/37
SUVmax(>3.277)	AUC	0.657	0.674	0.539	0.726
P value		0.0359	0.0345	0.2971	0.0626
SUVmean(>2.15)	AUC	0.667	0.581	0.593	0.722
P value		0.0323	0.0008	0.4946	0.0075
P/M ratio(>3.632)	AUC	0.672	0.535	0.603	0.738
P value		0.0452	0.02523	0.3576	0.1355
Combined parameter	AUC	0.793	0.772	0.692	0.852

AUC, Area Under Curve; Combined parameter = SUVmax(>3.277)+SUVmean(>2.15)+P/M ratio(>3.632), P values are calculated for combined parameter model versus each single parameter.

The bold values provided means the significant meaning in statistics because their P values are less than 0.05.
