Semi-parametric and parametric (Weibull) cox proportional hazard models of sero-reversion. Prob50% indicates the parametric estimate of time when 50% of the sero-positive cohort has become sero-negative. A Overall rate of sero-reversion for IgM or IgG. B Comparison of pauci- and asymptomatic vs. clinically-defined COVID cases. C Comparison of rates of IgM vs IgG sero-reversion. D Comparison of sero-reversion rates based on follow-up testing using the Syntron test targeting antibodies to nucleocapsid proteins and the Teco test targeting a combination spike and nucleocapsid proteins
