Pattern of fitted glucose concentrations during the first 3 h after birth. Restricted cubic spline curves were fit from initial glucose concentrations from term, appropriate size for gestational age newborns in the Beckman and Vitros Analyzers. (A) Fitted glucose concentrations and 95% confidence intervals from newborns using Beckman and Vitros Analyzers. (B) Fitted glucose concentrations and 95% confidence intervals from newborns using Beckman and Vitros Analyzers, after 5 mg/dL was added to the Vitros glucose concentration spline curve.
