a
Frequency of communication [mean (SD)] with all listed first- and second-degree relatives on a four-point Likert scale ranging from 1 (not at all) to 4 (a lot).
b
p-Value and confidence interval comparing intervention and control groups using mixed model analysis controlling for baseline value of outcome measure. Only the OR and 95% CI for the analysis summarizing over all time periods is presented.
c
Significant effect moderation: pregnancy (age ≤40 years), p=0.064, coefficient and 95% CI of interaction term, −0.18 (−0.36, −0.01).
