Predicted probabilities for child unmet dental needs and parenting stress by parental social support level. Note: Results shown are based on models reported in Additional file 1: Table S5; † indicates that, at a specific level of parenting stress, the predicted probabilities of child unmet dental needs for each level of support are significantly different (p < 0.05) based on estimated average marginal effects. Because instrumental support is a continuous variable, only results for the 25th and 75th percentile values are shown for ease of visualization. However, the corresponding statistical significance tests were based on all values of instrumental support—not just the difference between those two percentiles—for each specific level of parenting stress
