    Snippet: The sample size was calculated by taking variability of proportion of 18% from the average of 450 pregnant women who attend antenatal clinic per month in the hospital. 13 Using Open Epi software package for the determination of sample size and design effect of 1.5 at error margin of 5%, the final minimum sample size was calculated as 227. After considering 10% non-response rate for any unpredictable events, the final required sample size was 249......
