aAll continuous data are presented as mean (±SD).
b P values refer to Wilcoxon test. * P > 0.05; CI 95%.
cPSS, Perceived Stress Scale; positive mean change values represent an increase in perceived stress.
dSF-36, Medical Outcomes Study 36-Item Short-Form Health Survey; positive mean change values represent an increase in health related quality of life.
