Changes in RHI in both groups (a) and the comparison of improvement in RHI (b). Percent change in RHI [RHI after 24 weeks—RHI before treatment]/RHI before treatment. RHI values significantly improved in the teneligliptin group; the percent change in RHI was also significantly greater in the teneligliptin group. RHI reactive hyperaemia index
