  • All numbers and percentages are weighted to allow for the stratified sample, and CIs allow for clustering.

  • a For diarrhea, ORs are adjusted for month (ie, infant's age), mother's age at delivery, mode of delivery, and mother's education. For LRTI, ORs are adjusted for month (ie, infant's age), infant's gender, mother's age at delivery, mode of delivery, household income, whether the infant was first-born, mother's (current) smoking status, and family history of asthma.

  • b PAF = [(158/186) × 0.59/1.59] = 31%.

  • c PAF = [(158/186) × 1.70/2.70] = 53%.

  • d PAF = [(429/539) × 0.45/1.45] = 25%.

  • e PAF = [(429/539) × 0.52/1.52] = 27%.
