 The study is designed to have power of more than 09 to detect a 200 increase in triage for the intervention group compared with a 300 triage in the control group two-sided alpha005. Based on PHC records13 we estimated that CHWs would enroll an average of 30 women in six months, of which 4 will be positive . Correlation induced by CHWs is included in sample size calculations assuming an intra-class correlation coefficient of 010, resulting in a sample of 120 CHWs per arm, and a total of approximately 7200 women enrolled.
