INS and type 2 diabetes mellitus: During a median 12.0 months follow‐up, similar glycemic control effects were found between the once‐daily basal insulin and the twice‐daily premixed insulin regimens, with less weight gain and fewer hypoglycemic episodes observed in the basal insulin group, which indicates that the once‐daily basal insulin regimens with concomitant non‐insulin medication might be a preferred treatment pattern when switching to insulin treatment for the failure of non‐insulin medications in Chinese T2DM patients.
