Power Calculation
Due to logistics ,we did not achieve the desired sample size of 2700 but
rather 67.3% of the required sample size. However we calculated the
power of the study in the post-hoc analysis where we reached 94% and
81% power for the stillbirth rate and early neonatal death rate
respectively. Since both these measures were part of our primary
outcomes, our study is adequately powered with the sample size of 1817
