RYGB, Roux-en-Y gastric bypass; RYGB-FMRR, Roux-en-Y gastric bypass plus fenofibrate, metformin, ramipril, and rosuvastatin; SD, Sprague Dawley; SHAM, sham surgery (laparotomy); UAER, urinary albumin excretion rate.
Body weight was assessed at 8 weeks after intervention, while plasma glucose and urinary albumin excretion were assessed at 4 weeks post-intervention.
Values are given as mean ± SD.
Statistical significance of within-group differences are derived from multiplicity-corrected (Benjamini-Hochberg) paired t-tests.
Statistical significance of between-group differences are derived from multiplicity-corrected (Benjamini-Hochberg) unpaired t-tests.
