  1. [a] Non-inferiority margin (∆) = -10 where inference drawn is designated by: S = superior; NI = non-inferior; U = insufficient evidence. [b] Scores adjusted for correlation of observations; site- and provider-level characteristics (random effects); counseling mode; and patient age, education, first prenatal visit, and total number of prenatal visits (fixed effects). [c] Includes only women at six to nine months of pregnancy. *Significant at p < 0.05. Note: Upper limits of the confidence interval are not interpreted for non-inferiority analyses.
