  1. Based on estimated marginal means.
  2. Adjusted for background information (age and gender) and related non-nutritive sucking habits (thumb sucking and pacifier use).
  3. **The mean difference is significant at the 0.05 level.
  4. bAdjustment for multiple comparisons: Bonferroni.
  5. *P < 0.05.
  6. Dependent variable: Intercanine width (mm).
  7. Boldface data are the mean differences (95% CI) that are significant at the 0.05 level.
