FIG 3.

Analysis of RSV disease symptoms in relation to acute-phase serum neutralization titers. (A) Self-reported start and end dates of disease symptoms were recorded. All data points represent individual participants, and lines indicate means and 95% confidence intervals. (B and C) Plots showing the correlation between acute-phase serum neutralization titers (PRNT60) and duration of coughing (B; n = 37) and rhinitis (C; n = 36) for RSV-infected participants. For some participants, only the start date of coughing and rhinitis was recorded, and they were excluded from the analysis (n = 3 and n = 4, respectively). Data were assessed by Spearman correlation. PRNT, plaque reduction neutralization test.
