1 Proportions indicate the percentages of women who selected this response to a closed-ended question on frequency of social and emotional support that included seven possible responses. Authors analyzed all seven responses collectively using a mixed effect linear model; we report a HomVEE-calculated effect size and p-value associated with the individual response.

2 Statistical significance is based on the authors’ analysis using an independent t-test.

3 Statistical significance is based on the authors’ analysis using a mixed effect linear model. Negative effect is favorable to the intervention.

Authors analyzed all seven responses collectively using a mixed effect linear model; we report a HomVEE-calculated effect size and p-value associated with the individual response. Negative effect size is favorable to the intervention.
