  1. Model (1) unadjusted, model (2) adjusted for respondent’s characteristics (age, education, parity, wealth quintile) and location, with interviewer clustering accounted as a fixed effect. Both models accounted for clustering of individual responses within individual women (interview)
  2. FPH full pregnancy history module, FBH+ full birth history module with additional questions on pregnancy losses
