  • a Numbers in parentheses represent SD. The means for the baseline and laboratory follow-up are based on a sample size of 169; means for the 6-month follow-up are based on 151 women.

  • b Significant pre-post by point estimate interaction [F(1164) = 19.36, P < 0.0001] comparing baseline and the laboratory follow-up.

  • c Significant pre-post by range interaction [F(1164) = 18.01, P < 0.0001] comparing baseline and the laboratory follow-up.
