Estimated associations between income-to-needs and Expressive Language for the three child care groups. The slope of this association was significantly different (p < .05) for children in higher quality child care compared with children not in child care, as well as for children in lower quality child care compared with children not in child care (see Table 3). The vertical line represents the upper threshold for the region of significant difference in Expressive Language scores for children in higher quality child care compared with those not in child care.
