  1. (aM – mean, SD – standard deviation, bCI – confidence interval. Mixed-effects regression models with robust standard errors, due to the small sample size, were performed: a – considering repeated measurements in the two separate studies; b – considering the above-mentioned repeated measurements, along with differences between the two studies and intra-subject correlation, on grounds of the cross-over study design. All statistical calculations were controlled for the studied patients’ age and sex)
