Changes in e’ and E/e’ between baseline and 24 weeks later. The e’ velocity and E/e’ ratio were comparable between sitagliptin and voglibose groups at baseline. The e’ velocity and E/e’ ratio showed no changes between baseline and a mean of 24 weeks later in both groups. There was also no significant difference in the magnitude of the changes in e’ velocity and E/e’ ratio between the two groups. e’, mitral annular early diastolic velocity; E/e’, ratio of mitral inflow velocity to e’ velocity; W, weeks
