Power calculation: Minimum Detectable Effect Size for Main Outcomes Assuming an attrition-adjusted sample of 700 women (400 women in “with husband invitations” arm and 300 women in “without husband invitations” arm) as described above, we will have 75.9 percent power to detect a 20 percent decrease in the modern contraceptive prevalence rate in the intervention arm from 50 percent to 60 percent (𝛼=0.05). Assuming an attrition-adjusted sample of 700 women (400 women in “with husband invitations” arm and 300 women in “without husband invitations” arm) as described above, we will have 85.61 percent power to detect a 10 percentage points increase in the intervention arm from 20 percent to 30 percent (𝛼=0.05).
