Cluster C presented a worst response to bariatric surgery after 1 year of follow-up. Recovery from hepatic steatosis and evolution of BMI, waist/hip ratio (WHR), GGT, glucose, triglycerides, alkaline phosphatase, and high-density lipoprotein (HDL) levels, 1 year after bariatric surgery in patients from Cluster C vs Clusters A + B. The data are expressed as percentage of the value before surgery (normalized to 100%). Values represent the means ± SEM. Asterisks indicate values that significantly differ between Cluster C and Cluster A + B (t test: *P < 0.05, **P < 0.01).
