Average Performance of Immune Status-Discriminating Models in 5-Fold Cross-Validation

Model	AUC (95% CI)	Accuracy
Model A (follow-up point 1) (141 observations: 55 primary cases and 86 secondary cases)	0.90 (0.83–0.96)	0.84
Model B (follow-up point 2) (141 observations: 55 primary cases and 86 secondary cases)	0.95 (0.92–0.98)	0.86
Model C (both follow-up points) (282 observations: 55 primary cases and 86 secondary cases)	0.93 (0.90–0.96)	0.85

Abbreviations: AUC, area under the curve; CI, confidence interval.
