INS and cryohydrocytosis: Basal glucose production rates (Ra Glucose) were significantly higher in CHC patients (Figure 1D) although endogenous glucose production (EGP), reflecting hepatic insulin sensitivity and measured following low‐dose insulin infusion, was similar between CHC and healthy control subjects (0.71 ± 0.10 vs 0.66 ± 0.68 mg/kg/min, P = 0.72) (Figure 1D).
