Figure 4.

Serologic correlates against polymerase chain reaction–confirmed influenza infection. Odds ratios were determined by analysis of PVN IC95 and NAI IC50 antibody titers associated with H3N2+ cases and controls. Stata 15 was used to generate this figure. Abbreviations: for the pseudoviruses corresponding to the following strains: SC16 = A/South Carolina/NHRC 75458/2016 (H3N2); MW99 = A/Moscow/20/99 (H3N2); WY03 = A/Wyoming/03/03 (H3N2); TX12 = A/Texas/50/12 (H3N2); and CA09 = A/California/7/2009 (H1N1); NAI, neuraminidase inhibition; PVN, pseudovirus neutralization.
