  1. N (column %) unless indicated. N = number of households/mothers with conditions specified as “any” or “all” multiples as there were few discordant between twins in consent (i.e., 17 twins had discordant consent status with their co-twin). There were few triplets (33 sets consented, 2 not) and quadruplets (none consented, 1 set consented) so data not shown
  2. p-value by chi-square or Fisher’s exact test (for n < 5)
