Fig. 2: Early Zinc levels (first 48 hours of life) by gestational age.
From: Improved linear growth after routine zinc supplementation in preterm very low birth weight infants
95% confidence and prediction intervals and residuals of first zinc level during the first 48 h of life versus gestational age among infants < 33 weeks gestational age or < 1500 g birth weight in Epoch-2, excluding those without congenital anomalies or comfort care only. Quadratic regression analysis. Adjusted R2 = 0.2921, n = 228, P < 0.0001. Equation: Zn = 5.63727 −0.26622 X GA + 0.00370 x GA2. Zn Serum zinc level, GA gestational age (weeks).
