Association between feeding method and IQ or SI using logistic regression analysis.

Feeding Method	IQ average or below	IQ above average	OR (95%CI)	p value	SI ≤140	SI > 140	OR (95%CI)	p-value
	N (%)	N (%)			N (%)	N (%)
Bottle-fed	17 (77.3)	5 (22.7)	1.00		9 (45.0)	11 (55.0)	1.00
Breastfed	24 (64.9)	13 (35.1)	2.24 (0.64–7.91)	0.209	8 (21.6)	29 (78.4)	2.81 (0.84–9.43)	0.095
Mixed-fed	36 (69.2)	16 (30.8)	1.65 (0.49–5.49)	0.418	14 (31.1)	31 (68.9)	1.67 (0.55–5.09)	0.370

CI, confidence interval; IQ, intelligence quotient; OR, odds ratio; SI, social intelligence.
