ANC: Antenatal care; LEAP 1000: Livelihood Empowerment Against Poverty 1000 program; NHIS: National Health Insurance Scheme; PMT: Proxy means test. Models adjusted for PMT score, parity, improved source of lighting in the household, number of children under 5 years old in the household, district of residence, year of birth, infant born in the rainy season, and month of birth. Standard errors clustered at household level. Boldface results are those with a p-value less than 10%
