[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] Total number of messages by category include: prenatal care (n = 5), birth preparedness (n = 7), danger signs during pregnancy (n = 9); clean delivery (n = 2); newborn care (n = 6); communication techniques (n = 6). [d] Includes only women at 6 - 9 months of pregnancy. [e] Excludes additional time for women who participated in individual counseling following group session. * Significant at p < 0.05. Note: Upper limits of the confidence interval are not interpreted for non-inferiority analyses.
