  1. Note: There was a higher placental weight in the mild disease group compared to controls, but not in the severe disease group. Otherwise, there were no significant differences in gestational or delivery factors that might affect gene expression. Patients in mild and severe groups were ill at similar ages. 1Mann-Whitney test; 2Fischer's exact test; 3chi-square test; 4ANOVA.
