- This table shows the sensitivity, specificity, accuracy, LR+ and LR- calculated for different ratios of IgG/IgM for the diagnosis of secondary dengue fever
- Abbreviations: LR+ positive likelihood ratio, LR- negative likelihood ratio
- aMost useful value to diagnose secondary dengue. 1.10 is chosen as the most accurate ratio of IgG/IgM to diagnose based on all the variables used here
- ∞ value cannot be ascertained
