a
Model included race/ethnicity as the moderating variable of interest.
b
Model controlled child’s insurance status, caregiver educational attainment because educational attainment was higher in the PVP study arm compared to the Control study arm (p = 0.009), age of child at visit because it was lower in the PVP study arm compared to the Control study arm (p = 0.062), and the number of caregivers present and perception of child’s health because they were significantly correlated with the total number of questions asked (p = 0.001 and 0.060, respectively).
