Women who breastfed for 6 months or more had a 36% lower risk of developing BC ( P = 0.057; borderline significance).
Women who breastfed for 6 months or more had a 36% lower risk of developing BC ( P = 0.057; borderline significance).
The protective effect found in breastfeeding women did not reach statistical significance due to the reduced number of women who reported breastfeeding for a prolonged period of time (⩾6 months).
Therefore, weak and borderline significant associations should be interpreted with caution as they may not be associated with the outcomes under study.
