  1. * p < 0.05
  2. atested for single versus two parents
  3. bThere were 47 mothers and 6 fathers in the experimental group; there were 48 mothers and 6 fathers in the control group. This is the reason that the sum of the figures in the first three rows is not 49 and 50.
  4. ctested for mothers and not for fathers, as both groups had only 6
