Figure 5.

Pairwise spearman rank correlation coefficients of serum and respiratory SARS-CoV-2–specific neutralization, RBD binding antibody levels, participant age and severity (ie, in increasing rank order), and binding antibody levels in serum and nasal wash collected at the first study visit in SARS-CoV-2–infected participants (n = 25). The narrowness of the ellipse and intensity of the color indicate the strength of a given correlation coefficient, and the corresponding numerical values are defined by the vertical bar on the right. Abbreviations: Ig, immunoglobulin; Neutr., neutralization; RBD, receptor-binding domain; Resp., respiratory; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
