Extended Data Fig. 3: Kinetics of SARS-CoV-2 specific antibody responses in COVID-19 convalescents during the 480 days follow-up.
(A), (B) and (C) Kinetics of anti-RBD IgA, anti-RBD IgM and anti-N IgG during the 480 days follow-up. (D) and (E) Kinetics of anti-RBD IgG and MN titers of the COVID-19 patients with different clinical spectrum during the 480 days follow-up. The black solid line represents the fitted curve obtained using the LOESS (locally estimated scatterplot smoothing) curve fitting polynomial regression. Gray band areas represent 95% confidence intervals. Specimens with OD values ≥ 2.5 were assigned a value of 2.5 for anti-RBD IgA, and OD values ≥ 1.5 were assigned a value of 1.5 for anti-RBD IgM. MN titers ≥ 320 were assigned a value of 320. Dotted lines indicate the limit of detection.
