Primary outcome: stress
Regarding the primary timepoint (T2) for the primary outcome stress, there was no significant group by time interaction, (Distribution of primary outcome DASS-21 stress scores between baseline (T1), primary timepoint post-intervention (T2), and follow-up (T3) for coherent breathing (blue) and placebo breathwork (orange) groups. White dots are mean DASS stress scores for each group at each timepoint, and white error bars represent 95% confidence intervals (Furthermore, when analysing all three timepoints (T1, T2 and T3), there was no significant group by time interaction, (
