  • ORs are presented for the presence of hemorrhages among those with the risk factor (<2 years, boy gender, CPR, and coagulopathy) to those without. In the face of the zero observations, ORs were estimated by adding 0.5 to each value. The percentages in parentheses have used the risk factors as the denominator.
