Model-based predictions of time to seronegativity from symptom onset. A, Comparison of the 3 tested antibodies against the spike protein (S; blue), receptor-binding domain (RBD; green), and nucleoprotein (N; red) for the gamma-plateau (top) and the gamma-decay (bottom) models. B, Differences between the gamma-plateau (blue) and gamma-decay (red) models for the 3 tested antibodies: S (top right), RBD (bottom), and N (top left). Colored lines represent median estimates of the posterior density, while the shaded ribbons represent 95% confidence intervals. Abbreviation: MSD, Meso Scale Discovery assay.
