Extended Data Fig. 1: Correlation between PGT121 neutralizing and binding antibody concentrations.

Concordance between PGT121 concentrations measured by binding and neutralizing antibody assays using pseudovirus strains CNE30 (a) and X2088_c9 (b). The dotted line is the identity line. Solid line is the trend line. Data are colored by participant. Lin’s concordance correlation coefficient is a measurement of accuracy and precision which is used to assess agreement between two sets of measurements.
