Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that breastfeeding lowers a mother's blood pressure?

Unclear. Several sources associate breastfeeding with lower maternal blood pressure, but each covers only a narrow slice: one rural Japanese cohort at one month postpartum found lower systolic pressure, a review of women with hypertensive disorders found lower systolic and diastolic pressure, and two reviews list decreased blood pressure or lower hypertension risk among breastfeeding benefits. No retrieved item settles the general claim at full strength.
