Fig. 2. Effects of EE on glucose and insulin tolerance tests in mice: (a) OGTT; (b) AUC for OGTT; (c) ITT (results are presented as fold change, compared to fasting glucose); (d) AUC for ITT. Normal: normal group; Model: diabetic model group; EE-L: 150 mg kg–1 EE-treated diabetic group; EE-M: 250 mg kg–1 EE-treated diabetic group; EE-H: 350 mg kg–1 EE-treated diabetic group. *P < 0.05, **P < 0.01 and ***P < 0.001 vs. normal group; #P < 0.05 and ##P < 0.01 vs. model group.
