Baseline values and absolute within-group changes after the supervised, gym-based training (phase I, 3 and 6 months) and the home-based training (phase II, 9 and 12 months) in PRT+WL and sham+WL for BMI, waist circumference, triglycerides, gamma-glutamyl transferase and FLI and the net between-group differences for change relative to baseline

  • All baseline values are unadjusted means±SDs. All change values are unadjusted means (95% CI) and expressed as absolute changes from baseline. Mean net differences (95% CI) were calculated by subtracting within-group changes for PRT+WL from within-group changes from WL.

  • *P<0.05, **p<0.01, ***p<0.001 within-group change from baseline.

  • †P values represent group-by-time interaction from linear mixed models adjusted for baseline values.

  • BMI, body mass index; FLI, fatty liver index; PRT, progressive resistance training; WL, weight loss.
