Fig. 1: Salivary anti-influenza virus activity.
From: Enhanced anti-influenza virus activity of saliva following toothbrushing
The anti-influenza virus activity of saliva was measured at three time-points: before, 5 min after, and 1 h after toothbrushing. The horizontal axis represents the saliva collection time, and the vertical axis indicates anti-influenza virus activity. a Analysis of saliva from all participants (n = 16). b Analysis of saliva from participants with low antiviral activity before toothbrushing (n = 8). c Analysis of saliva from participants with high antiviral activity before toothbrushing (n = 8). The Wilcoxon signed-rank test, corrected using the Bonferroni method, was used for statistical analysis. The significance threshold was set at 0.0167 (0.05/3). Different letters a, b denote statistically significant differences (P < 0.0167).
