Figure 3: Likelihood ratio plots for all assays. The positive and negative likelihood ratios ( -axis) are plotted against the titer of the antibodies ( -axis). Likelihood ratios are shown at the cutoff (red line) and at the highest positive likelihood (orange line). NOTE: likelihood ratios are illustrated based on values depicted by the software and displayed in a graph. Likelihood ratios between two data points might be different from the real values. QF = QUANTA Flash; FEIA = fluoroenzyme immunoassay.
