I found the studies the article was based on. Two in the same issue:
Prentice A.
Calcium supplementation during breast-feeding.
N Engl J Med. 1997 Aug 21; 337(8): 558-559. No abstract available.
PMID: 9262501; UI: 97390207.
Kalkwarf HJ, et al.
The effect of calcium supplementation on bone density during lactation and
after weaning.
N Engl J Med. 1997 Aug 21; 337(8): 523-528.
PMID: 9262495; UI: 97390201.
Do they also list 5 mos as "age of weaning" OR do they list 5 months as the
average age of weaning for the study groups?
There is a big difference.
