a,b,c Median or percentage values within a row with unlike superscript letters were significantly different between time points for each surgical model, as tested by paired pairwise post hoc comparisons with Holm-Bonferroni correction or paired McNemar’s test.
*Significant differences between GBP and AGB. Glucose intolerance is defined as either fasting hyperglycemia (1 g/l≤G<1.26 g/l) or 6%≤HBA1c<6.5%; dyslipidemia is defined as a patient with treatment (statin or fibrate) or hypertriglyceridemia ≥1.5 g/l or hypoHDL<0.5 g/l; high blood pressure (HBP) is defined as a systolic blood pressure >140 mmHg and/or a diastolic blood pressure>90 mmHg or patients with an anti-hypertensive treatment; obstructive sleep apnea (OSA) is defined as an Apnea-Hypopnea Index >5/h with or without treatment.
