Fig. 2. Dynamics of NAbs response to SARS-CoV-2.

A The positive rate of NAbs (measured by sVNT) stratified by time post onset. A NR₂₀ value (neutralization rate at 1:20 sample dilution) of ≥20% was regarded positive. B Boxplot of the titers of NAbs stratified by time post onset. C The trajectories of NAbs in patients. Each gray line represents the trajectory of a patient. The blue line is the loess smooth curve of the trajectories. D Decline of NAbs over time in patients with peak logit NR₂₀ > 1.3 (25^th percentile of peak distribution). Each gray line represents the post-peak trajectory of a patient. The blue line is the loess smooth curve of the trajectories
