Dose–response curves depicting the breaking point between the 25 μg bisphenol A (BPA) and 250 μg BPA per kilogram body weight per day within two representative end points in the mammary gland. Higher values occur before the break (250 μg BPA) and lower values after the break (25 μg BPA) (scale bars represent 2 mm). a | Standard deviation of width (mean variation in ductal thickness). A low value indicates more tubular structures. A high value indicates more budding structures. b | Thickness (average local thickness of the gland ductal tree).
