Performance of the all-inclusive models to discriminate primary from secondary dengue

Marker	AUC (95% CI)	Accuracy	Sens.	Spec.	PPV	NPV
Panbio Indirect IgG	0.90 (0.88–0.92)	0.85	0.91	0.78	0.84	0.86
In-house capture IgG	0.86 (0.83–0.89)	0.84	0.89	0.77	0.84	0.84
In-house capture IgM	0.55 (0.51–0.59)	0.58	0.81	0.28	0.60	0.53
In-house capture IgM/IgG ratio	0.88 (0.85–0.90)	0.84	0.90	0.77	0.83	0.85

For this and subsequent similar tables AUC area under ROC curve, Sens sensitivity; Spec. specificity, PPV positive predictive value, NPV negative predictive value. Cut-offs were selected to maximize accuracy as described in the statistical methods section
