  1. All values are means ± SDs. There were no significant differences between PW and HW groups for all measures at baseline on the basis of an unpaired t test or a Mann–Whitney U test. ∆ indicates the change from baseline to week 4. Significant differences between baseline and week 4 within each group were determined with the use of a paired t test (*P < 0.05; **P < 0.01; ***P < 0.001). P values were obtained with the use of a general linear model adjusting for the value at baseline as a covariate. PW, plain water; HW, H2-rich water; BAP, biological antioxidant potential; d-ROMs, derivatives of reactive oxygen metabolites; 8-OHdG, 8-Oxo-2-deoxyguanosine.
