Impact of preoperative carbohydrate loading on gastric volume in patients with type 2 diabetes

Figure 4 Comparison of blood glucose in four groups of patients at T0 and T2. In groups 1, 2, and 3, blood glucose levels increased significantly at T2 compared with that at T0. In patients receiving 300 mL of the carbohydrate drink (group 3), the blood glucose level at T2 increased by > 2 mmol/L, which was significantly higher than that in control and group 1 (^aP < 0.05, T0 vs T2; ^bP < 0.05, group 3 vs control; ^cP < 0.05, group 3 vs group 1).
