Women Who Returned the
12-Month Questionnaires
vs Women Who Did Not
We compared women who
were included in the analysis
of outcomes at 12 months’
postpartum with those who
did not return the follow-up
questionnaires at 12 months’
postpartum. Table 5 shows
no statistically signifi cant difference
between women in
the intervention group who
were included in the analysis
and those who did not return
the 12-month questionnaires.
Women in the usual-care
group who did not return
the 12-month questionnaires,
however, were more likely to
be poor and uninsured postpartum.
The impact of these
differences is unknown.
