Table 4.

Pairwise comparison of the association between the intercanine width and the duration of pure breastfeeding

Variables	Intercanine 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			0.003*
>6 months - Never	0.608**	0.197	0.006*	0.134	1.081
>6 months - ≤6 months	0.541**	0.184	0.010*	0.099	0. 983
≤6 months - Never	0.067	0.173	1.000	−0.349	0.483

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: Intercanine width (mm).

Boldface data are the mean differences (95% CI) that are significant at the 0.05 level.
