  1. Abbreviation: CI confidence interval
  2. aIn the random intercept model, the HFI index is modeled as a linear function of visit clustered at household level. The model allows missing information in the follow-up assessments, therefore, the observations used in the analysis varied from 1 to 6 per household and averaged at 5.3 per household
