a Dominant NIC grade. The dominant NIC grade was similar between the DM and non-DM groups (p = 0.59). bMaximum NIC grade. The maximum NIC grade was similar between the DM and non-DM groups (p = 0.94). c Minimum NIC grade. The minimum NIC grade was significantly lower in the DM group than in the non-DM group (p = 0.002). In the DM group, 47 lesions (32%) demonstrated the minimum NIC of grade 0. d Maximum yellow color grade. The maximum yellow color grade was similarly distributed between the DM and non-DM groups (p = 0.78). eThrombus Adhesion. The rate of thrombus adhesion was similar between the DM and non-DM groups (44% vs. 39%, p = 0.32). DM diabetes mellitus, NIC neointimal coverage
