Comparison of parent and child outcomes for families who received IYPB and usual care (UC) pre-intervention (T1), post-intervention (T2), and follow-up (T3) with regression coefficients, and 95% confidence intervals for multiple linear regressions on imputed data controlling for site and baseline score when possible

Regression results of interaction analyses for mothers divided into groups based on pre-intervention (T1) scores of presented measures. Results compare mothers at follow-up who received the IYPB program to those who received usual care within the groups scoring in the lowest 25th and 50th percentiles and the highest 50th and 75th percentiles
