Re: “Chronic Particulate Exposure, Mortality, and Coronary Heart Disease in the Nurses’ Health Study”

Puett et al. recently found an error in their Journal article (1). On page 1163 and in Tables 4 and 5, “person-years” should be substituted for “person-months.” The Journal and the authors regret these errors.
