Fig. 1: Correlations among different measurements of NAbs and IgG against SARS-CoV-2.

From: Dynamics of neutralizing antibody responses to SARS-CoV-2 in patients with COVID-19: an observational study

Fig. 1

A NAbs IC50 titer by focus reduction neutralization test (FRNT) vs NAbs IC50 titer by surrogate virus neutralization test (sVNT); B NAbs IC50 titer by FRNT vs logit of sVNT neutralization rate at 1:20 dilution of sera (logit NR20); C NAbs IC50 titer by sVNT vs logit NR20; D NAbs IC50 titer by FRNT vs the level of total binding IgG. The blue lines are the regression lines between two measurements estimated by Deming regression. ρ Spearman’s correlation coefficients, S/CO ratio of the chemiluminescence signal over the cutoff value
