Projected and observed exclusive breastfeeding for age groups 12–13 to 34–35 months of age, with reference lines of 10% (short dashes) and 1% (long dashes) prevalence in EmrD. Observed non-zero exclusive breastfeeding rates throughout second and third year of childhood in EmrD, in particular observed rates of nearly 5% in Pakistan (code = 128) and Egypt (code = 54, multiple surveys) for age groups 12–13 to 16–17 months of age, suggest systematic measurement error. High overall variability show limitations of 24-hour recall.
