Insulin was administered for 24 hours, during total parenteral nutrition, at a dosage to maintain a moderate hyperglycemia in CIT, and normoglycemic blood glucose levels in IIT (9.3±0.5 vs 6.5±0.3 mmol/L respectively, P<0.001; coefficient of variation, 9.7±1.4 and 10.5±1.1%, P = 0.43). The gene discussed is INS; the disease is Hyperglycemia.
