Fig. 2: Nonparametric coefficient of determination (R2) between baseline RSV pre-F binding antibody titers and neutralizing antibody titers among pediatric participants.
From: Correlates of risk of respiratory syncytial virus disease: a prospective cohort study

Correlation between binding and neutralizing antibody titers measured at baseline among (A) all pediatric participants 6 months–17 years (n = 1355) and (B) pediatric participants 6 months–4 years (n = 323). Data are presented as a scatter plot of individual participants’ binding and neutralizing antibody titer measurements overlaid with a blue correlation trendline ± the standard error of the smooth as a 95% confidence interval shown in gray. Abbreviations: log10-AU/mL log10-transformed arbitrary units per milliliter, log10-IU/mL log10-transformed international units per milliliter, RSV respiratory syncytial virus, R2 nonparametric coefficient of determination.
