Data of variables marked with † are presented as median (IQR), otherwise as mean (SD).

*Cohen’s d effect size.

†P value testing for differential change of heart rate at the underlying time point with respect to T1 by using GEE model.

‡The Cohen’s d effect size corresponds to the standardised mean difference of the mean changes at the underlying time point with respect to T1 between the intervention and control groups.

§Nature log-transformed before subjected to independent t-test.

¶Independent t-test.
