Statistical Analysis Before addressing the research question, descriptive statistics and summary graphics such as histograms will be prepared and examined for outcomes and demographic variables. All analyses addressing the study research questions will use the "intention to treat" principle, thus comparing the original intervention group to the original nonintervention group, even if individuals have withdrawn from the study or shifted to another group. The analysis plan and presentation of results will follow the recommendation of the CONSORT statement. In this study the primary outcome is continues (blood loss), therefore, median and inter-quartile ranges will be computed as part of descriptive data analysis to understand the distribution of the outcome variables and to assess the need of data transformation or adoption of nonparametric tests, including Mann-Whitney U tests. Means for the two groups will be compared by the two-sample t-test. A similar analysis will be performed for the duration (in minutes) of the third stage of labor.
