In the article by Weisskopf et al, “A Prospective Study of Bone Lead Concentration and Death From All Causes, Cardiovascular Diseases, and Cancer in the Department of Veterans Affairs Normative Aging Study,” which published online September 8, 2009, and appeared with the September 22, 2009, issue of the journal (Circulation. 2009; 120:1056–1064), a correction was needed.
In trying to adjust finely for age at bone lead measurement the models were stratified on age at lead measurement in months, which resulted in over-stratification and the inadvertent exclusion of many participants. In order to include all participants, the analyses were modified without stratification, age was used as the time metameter, and the data were adjusted for age at bone lead measurement in the model instead. While a somewhat similar pattern is seen, particularly for patella lead and ischemic heart disease mortality, the results do not reach statistical significance. There is still no association with blood lead.
The authors regret the errors. The corrections have been made to the current online version of the article.
