The odds ratios are for the occurrence of the disorder listed on the left comparing those who had hyperEPO to those who did not.
* These are column percentages, EPO quartiles were determined on day 14
† Odds Ratios (95% confidence intervals) are adjusted for gestational age category
^ cerebral palsy subtype and MDI and PDI category odds ratios were modeled using multinomial logistic regression
