Model satisfied proportional hazards assumption across all 10 imputations (average p value=0.629).
*All variables were included in the adjusted model.
†House quality is a composite of the construction materials used to make the roof, walls and floor.
‡Household assets include bicycle, radio, ox cart and mobile phone.
