Breast Cancer Research

Table 3 Adjusted odds ratios^a and 95% confidence intervals for dichotomized dietary intake^b by family history category

	Sporadic or familial family history (n = 90)		Hereditary family history (n = 67)
	Median (g)	Odds ratio (95% confidence interval)	Median (g)	Odds ratio (95% confidence interval)
Protein
∘ Low	76.2	1.0	77.6	1.0
∘ High	93.5	3.0 (1.3–6.9)	91.0	0.4 (0.1–1.4)
∘ P value for interaction^c	<0.001
Animal protein
∘ Low	51.6	1.0	49.0	1.0
∘ High	66.4	4.3 (1.8–10.3)	69.6	0.5 (0.1–1.5)
∘ P value for interaction	<0.001

^aModels adjusted for age, body mass index, caloric intake, age at menarche, menopausal status, hormone therapy use, and vitamin D intake. ^bDichotomized at median value. ^c P value for interaction was obtained by including in the model of a dichotomized dietary variable x family history category interaction term.
