↵*Mixed effect linear regression was used to analyse change in and between clusters when data had normal distribution.
†All outputs were adjusted for potential confounders without any change in value. Covariates adjusted for were: distance from clinic to city hospital (km), population in village, if there were additional clinic in village, clinics with community midwife, clinics with laboratory and clinics with a regular checkpoint on the way to hospital.
‡Mixed-effect Poisson regression was used to analyse the change in clusters when data was not normal distributed.
