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 causes mothers to lose calcium from their teeth?

Unclear. Two items partially bear on the claim: a Chinese cohort study found breastfeeding mothers were about four times more likely to take postpartum calcium supplements, and a Korean study notes breastfeeding uses roughly 300–400 mg of calcium daily for milk production and links longer breastfeeding to tooth loss in older women. Neither measures calcium loss from teeth directly, so the evidence covers only part of the claim.
