Pulmonary Function in a Cohort of New York City Police Department Emergency Responders Since the 2001 World Trade Center Disaster
In the article, “Pulmonary Function in a Cohort of New York City Police Department Emergency Responders Since the 2001 World Trade Center Disaster,” published in the June 2011 issue, a portion of the 2007 data was omitted and is herein clarified.
In 2002, 11 of 206 subjects (5.3%) exhibited mild pulmonary dysfunction (60% to 80% of predicted; 95% CI: 3.0% to 9.4%). Upon reevaluation in 2007, the abnormalities had resolved in 4 of the 11 affected individuals (36.4%), whereas 6 individuals (54.5%) continued to exhibit mild pulmonary dysfunction, and 1 individual did not return for testing. Ten additional individuals (7.2%) of 139 returning subjects exhibited mild pulmonary dysfunction (95% CI: 3.9% to 12.9%), raising the number of affected individuals to 16 (11.5%; 95% CI: 7.2% to 18.0%). This increase in prevalence, however, was not statistically significant (McNemar test with continuity correction, P = 0.18) and does not affect the conclusions.
