  1. aMean ± sd and used t-test
  2. bAsset index: The household asset index was constructed using household asset data obtained from the SES questionnaire. From this asset related dichotomous variables, using polychoric principal components analysis in STATA software to produce a common factor score for each household. After ranking by their score, we divided first principal component score into quintile to create 5 categories where first category represents poorest and fifth category represents richest one
