Demographic, Obstetrical and Neonatal Information for Heparin versus Enoxaparin Groups. Statistical Significance is Based on the Logistic Regression. Continuous Variables Shown as Mean with Standard Deviation, Categorical Variables Shown as Number of Patients with Percentage of Group. NS = Not Significant; APGAR = Appearance, Pulse, Grimace, Activity, and Respiration scoring system
