Accuracy of 9/11 health reports debated

Anthony DePalma and Serge F. Kovaleski of The New York Times explore questions about the health data reported by the Irving J. Selikoff Center for Occupational and Environmental Medicine, which has overseen the treatment of thousands of ground zero workers. While the clinic's efforts have been called "well meaning," the resources needed to track and report data have been inadequate and caused many to question the accuracy of their findings. "Researchers in this field say that the clinic's data collection was so badly planned that its usefulness may be limited. Others say that doctors at the clinic, which has strong historical ties to labor unions, have allowed their advocacy for workers to trump their science by making statements that go beyond what their studies have confirmed."
