From: Alcohol consumption, endogenous estrogen and mammographic density among premenopausal women
Adjusted mean salivary estrogen by high (red line) and low (blue line) current alcohol intake aâc stratified by absolute mammographic density b, c among 190 premenopausal women. a Current alcohol intake: <1 alcohol drink/day, 17.55 pmol/l; â„1 alcohol drink/day, 20.70 pmol/l; p = 0.034. b Absolute mammographic density â€2.4 cm2: <1 alcohol drink/day, 17.67 pmol/l; â„ 1 alcohol drink/day, 19.09 pmol/l; p = 0.486. c Absolute mammographic density >32.4 cm2: â€1 alcohol drink/day, 17.53 pmol/l; >1 alcohol drink/day, 22.36 pmol/l; p = 0.033. All analyses used linear mixed models for repeated measures, adjusted for age (continuous), body mass index (kg/m2, continuous), number of children (continuous), previous oral contraceptives (categorical), and current smokers (categorical). One drink or unit is equal to 10 g alcohol. Mean salivary estradiol throughout menstrual cycle
