  1. Reproducibility of estimated infant feeding categories from the since-birth and short-time recall at week 6 and week 12 after birth, respectively. Cohen's kappa test was calculated as a measure of agreement (Κ, p) and one-sample test of proportion was calculated for further accuracy (proportion test, p).
  2. * One-sample test of proportion, level of agreement set to 0.7
  3. NA = Not applicable
  4. PA = Perfect agreement
