Data will be analyzed using PC SAS Version 9.1 (SAS Institute, Cary, NC). The two components of the study will be analyzed separately. The weight loss leg of the study will utilize an independent t-test in an effort to determine the relationship of weight loss (yes/no) to time to delivery. For the urobilinogen component of the study, we will utilize correlation techniques to assess the relationship of time to delivery and urobilinogen level. Significance will be determined at the 0.05 level.
