Receiver-operating characteristic curves of 1,5-AG and HbA_1c levels to predict coronary plaque rupture in diabetic patients with ACS. The areas under the curve of 1,5-AG (1/x) and HbA_1c levels were 0.658 (0.563–0.752, P = 0.002) and 0.587 (0.490–0.684, P = 0.087), respectively. 1,5-AG 1,5-anhydro-d-glucitol, HbA_1c hemoglobin A_1c
