Extended Data Fig. 4: Relationship between anti-RBD IgG antibody levels and neutralizing capacity.
From: Accelerated waning of the humoral response to COVID-19 vaccines in obesity
a-c, Correlation between NT50 and anti-RBD IgG (MFI) before (V3D0, a), 8 days after (V3D8, b) and 28 days after (V3D28, c) third dose booster vaccination. d-f, Ratio of (NT50/anti-RBD IgG (MFI))*1000 before (V3D0, d), 8 days after (V3D8, e) and 28 days after (V3D28, f) third dose booster vaccination. Each symbol represents an individual person (controls with normal BMI (n = 16), black; severe obesity (n = 22), magenta). Open symbols represent individuals with unquantifiable or undetectable neutralizing activity. For d-f, median values and interquartile ranges are shown. P-values from Mann-Whitney U tests.
