Sample size and sampling procedure A cluster randomized community trial proposes to assess the effectiveness of deploying CORNs to advance skilled birth attendance (delivery). A previous Demographic and health Survey (DHS) 2011 study showed that proportion of subjects who had an assisted delivery was 4% in rural settings. According to the health sector development plan IV of the country, it has been planned to increase the proportion of assisted delivery from 18.4% to 62% at the end of 2014/15 fiscal year. Hence, a pro-grammatically similar and important difference of 58% is expected after the deployment of CORNs.
