Figure 2

Longitudinal plot of all nucleocapsid-reactive donors with predicted slope (black dashed line) at mean observed peak S/CO in study of trajectory and demographic correlates of antibodies to SARS-CoV-2 nucleocapsid in recently infected blood donors, United States, June 2020‒June 2021. Shown are the overall dataset and a spaghetti plot of regression lines of S/CO values for each donor in the cohort. The natural log of observed peak values covered a range from ≈0 to ≈5.7, and the mean observation time was 101.7 days. Ln, natural log; NC, nucleocapsid; S/CO, signal-to-cutoff value.
