The positive effects of TGC on postoperative complications were driven by nondiabetic subjects ( @ % vs @ % , @ % CI , @-@ @ ; blood glucose @ @ vs @ @ mmol/L , not significant ; time in target range , @ % @ % vs @ % @ % , not significant ) , whereas no significant effect was seen in diabetic patients ( @ % vs @ % , @ % CI , @-@ @ ) despite significantly better glucose control in the perioperative group ( blood glucose , @ @ vs @ @ mmol/L , P < @ ; time in target range , @ % @ % vs @ % @ % , P < @ ) .
