Individual salivary CORT concentrations only showed a trend towards a positive correlation prior to solo versus choir singing under basal conditions (Basal 2 samples; r = 0.439, p = 0.078; Figure 4B ; nota bene: removing the two outliers reduced the positive correlation coefficient to r = 0.221 ( p = 0.43)).

We therefore compared OXT samples collected during choir singing between the two cohorts by performing a two-way ANOVA; the interaction effect between time (before and after signing) and cohort (Händel and Bach) did not reach statistical significance ( p = 0.78), wherefore we pooled both sets of results.
