Average antibody levels over time among SARS-CoV-2–infected Rutgers Corona Cohort participants, stratified by symptom severity. Plots show estimated average levels of (A) total antibody and (B) IgG over time with 95% confidence intervals based on symptom severity. Curves and 95% confidence bands were estimated for different levels of symptom severity by fitting a model with a spline function for time and a random intercept to account for repeated measures. Abbreviations: Ig, immunoglobulin; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
