Unadjusted and Adjusted Estimates for the Growth Rates Over the First Eight Years of Infection and Summary of the Cutoff Method Based on the .5% Threshold for the Four Largest Non-B Subtype Groups in Switzerland

				Cutoff of <.5%
Subtype	No. (%) of recent infections	Univariable model, Coefficient (95% CI)	Multivariable model, Coefficient (95% CI)	Sensitivity, %	Specificity, %	ROC, %	NPP, %
A (n = 185)	11 (7.1)	.197 (.121–.276)	.193 (.105–.276)	63.6	63.6	63.6	95.6
CRF01_AE (n = 173)	10 (5.8)	.210 (.142–.285)	.141 (.064–.217)	100.0	59.5	79.8	100.0
CRF02_AG (n = 185)	15 (8.1)	.159 (.081–.240)	.110 (.098–.220)	80.0	51.8	65.9	96.7
C (n = 131)	6 (4.6)	.150 (.069–.230)	.104 (.024–.175)	100.0	66.4	83.2	100.0

NOTE. The unadjusted and adjusted estimates for the growth rates over the first 8 years of infection are analogous to Table 1. The summary of the cutoff method based on the .5% threshold is analogous to Table 2. CI, confidence interval; NPP, negative predictive value; ROC, receiver operating characteristic.
