Multivariable models for NAFLD for >6 months lactation compared to 0–1 months of lactation.

Model	OR NAFLD	95% CI	p value*
Lactation >6 months, unadjusted	0.48	(0.25–0.94)	0.03
Model 1: Lactation duration categories + Baseline BMI + race + post baseline parity	0.46	(0.22–0.97)	0.04
Model 2: Model 1 + Baseline waist circumference	0.48	(0.23–1.01)	0.06
Model 3: Model 1 + Baseline diet & physical activity	0.50	(0.23–1.09)	0.09
Model 4: Model 3 + Baseline HOMA-IR	0.45	(0.21–0.98)	0.04
Model 5: Model 1 + Change in BMI	0.51	(0.23–1.11)	0.09
Model 6: Model 1 + Change in HOMA-IR†	0.44	(0.20–0.97)	0.04
Model 7: Model 1 + Change in waist circumference	0.51	(0.23–1.14)	0.10
Model 8: Model 1 + Change in physical activity	0.46	(0.22–0.97)	0.04
