Parametric variables are expressed as mean ± standard deviation, whereas nonparametric variables are expressed as median [interquartile range]. Percentage change relative to baseline means are indicated in round brackets. *Mean or median value is significantly different from that of baseline ( ) (compare within row and within group). #Mean or median value is significantly different from that of week 14 ( ) (compare within row and between group). aMean arterial pressure; bestimated glomerular filtration rate; caminotransferase aspartate; daminotransferase alanine; etotal antioxidant status.
