Diabetes recurrence after metabolic surgeries correlates with re-impaired insulin sensitivity rather than beta-cell function

Figure 1 Areas under the curves for oral glucose tolerance test; of rats at baseline, 4 and 12 wk after operations. ^aP < 0.05 vs Sham group at 4 wk postoperatively, ^cP < 0.05 vs Sham group at 12 wk postoperatively, ^eP < 0.05 vs SG-HFD group at 4 wk postoperatively, ^gP < 0.05 vs DJB-HFD group at 4 wk postoperatively. AUCOGTT: Areas under the curves for oral glucose tolerance test; SG: Sleeve gastrectomy; SG-LFD: SG rats with common low-fat diet; SG-HFD: SG with high-fat diet; DJB: Duodenal-jejunal bypass; DJB-LFD: DJB rats with LFD; DJB-HFD: DJB rats with HFD.
