Table 2 Performance of the all-inclusive models to discriminate primary from secondary dengue

From: Methods to discriminate primary from secondary dengue during acute symptomatic infection

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
  1. 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
