Fig. 3: Serum zinc level versus postmenstrual age among infants < 29 weeks gestational age in Epoch-2 in the growth cohort.
From: Improved linear growth after routine zinc supplementation in preterm very low birth weight infants
Blue circles represent serum zinc levels within the first 48 h postnatal while red circles represent levels at 3–4 days of life. Yellow diamonds show zinc levels at > 4 days of life before enteral zinc supplementation and green triangles represent zinc levels after >2 days of enteral zinc supplementation. The line shows the estimate from the quadratic regression analysis based on serum Zn levels within the 48 h postnatal among all infants (Fig. 2). Yellow diamonds are evenly distributed around the line, whereas many green triangles after 32 weeks postmenstrual age are below the line. Zn serum zinc level, GA gestational age, PMA postmenstrual age.
