Table 5 Raw (β1) and adjusted linear regression model 3 (β3) to evaluate the association between quartiles of ultra-processed food intake in calories and grams during the peri-pubertal period and %FGV/AFGV at 4 years after menarche in the follicular and luteal stage of the menstrual cycle.

From: Consumption of ultraprocessed foods and breast density in adolescence
