  • This analysis was performed by subtracting an assumed degree of prematurity from all premature infants, using 1, 2, and 3 mo as possible values and modeling postgestational age as the independent variable. The OR for prematurity changed little and was significant in all cases, suggesting that postgestational age alone cannot account for increased odds of developing an adverse event. Models were adjusted for age and gender of the patient.
