Table 5 Pairwise comparison of the association between the intermolar width and the duration of pure breastfeeding

Variables	Intermolar width (mm)		P-value^b	95% Confidence interval for difference
	Mean difference	Standard error		95% Confidence interval for difference
	Mean difference	Standard error		Lower bound	Upper bound
Duration of breastfeeding			0.002*
>6 months - Never	0.857**	0.274	0.006*	0.198	1.515
>6 months - ≤6 months	0.813**	0.258	0.005*	0.193	1.433
≤6 months - Never	0.044	0.249	1.000	−0.554	0.642

Based on estimated marginal means.
Adjusted for background information (age and gender) and related non-nutritive sucking habits (thumb sucking and pacifier use).
**The mean difference is significant at the 0.05 level.
^bAdjustment for multiple comparisons: Bonferroni.
*P < 0.05.
Dependent variable: Intermolar width mm.
