Extended Data Fig. 2: Comparison of the antibody responses of COVID-19 patients with different clinical spectrum within 28 d.a.o.
The positive rates and exact values of anti-RBD IgG (A), anti-RBD IgA (B), anti-RBD IgM (C), anti-N IgG (D) and MN titers (E). Statistical significance was measured using a Mann-Whitney two-sided test U-test. *P < 0.05, **P < 0.01, ***P < 0.001. ns, not significant. The line and error bar represent the mean and standard deviation for the anti-RBD IgG, while geometric mean titers and standard deviation for the MN titers. Black dotted lines indicate the limit of detection for anti-RBD IgM, and green dotted lines indicate the limit of detection for anti-RBD IgA.
