(A) Scatterplot of cord blood IL-6 in logarithmic format. The bar represents the median level for the group. (B) Proportion of newborns displaying at least one major adverse outcome represented by the black portion of the bar. Data analyzed by one-way ANOVA followed by Holm Sidak multiple comparison method (A) or chi-square test (B). Groups sharing one common letter are not statistically different at P>0.05.
