Odds ratios (and 95% confidence interval) of the outcome listed at the top of each set of columns among children who had a concentration in the top quartile (for gestational age and day specimen was obtained) of the protein(s) listed on the left on day 14 or days 7 and 14 relative to that of children who did not have an elevated concentration of the same protein(s). The multinominal regression models compare children whose scores were < 55 and those whose scores were between 55 and 69 to children whose scores ≥ 70, adjusting for gestational age (23-24, 25-26, 27 weeks). The results for the groups whose scores were < 55 are presented in Table 4. The results here are for children whose scores were between 55 and 69. Bold italic indicates odds ratios significantly < 1 and bold indicates odds ratios significantly > 1 (p < 0.01).
