Restricted cubic splines for the hazard ratio (HR) and 95% confidence intervals (CIs) of total intake of total dairy product consumption incidence of breast cancer in the “Seguimiento Universidad de Navarra” (SUN) cohort. The black line represents the HR, and the dashed lines represent the 95% CIs. A serving/day value of 0 was the reference value. Adjusted for height, years at university, family history of breast cancer (none, after 45 years, or before 45 years), smoking status (never smoker, former smoker, current smoker), lifetime tobacco exposure (pack-years), physical activity (METs-h/week), TV watching (h/day), alcohol intake (g/day, continuous), BMI (<25, 25–30, ≥30), age of menarche (<10 years, 10–11 years, 12–13 years, ≥14 years), age at menopause (<50 years, ≥50 years), history of pregnancy (age <25 years and nulliparous, age ≥25 years and nulliparous, first pregnancy before 25 years, first pregnancy between 25 and 30 years of age, first pregnancy being 30 years old or older), months of breastfeeding (continuous), use of hormone replacement therapy (yes/no) and its duration (continuous), energy intake (kcal/day), energy-adjusted intake of calcium, vitamin D, and saturated fat from non-dairy products (tertiles), coffee consumption (<1, ≥1), sugar-sweetened beverage consumption (never/seldom, ≥1 serving per week), and oral contraceptives (yes/no), as well as additionally adjusted for Mediterranean Diet Adherence (score Trichopoulou without alcohol and dairy product items) (continuous); p for nonlinearity = 0.048.
