Milloy request NEJM retraction: If PM2.5 kills, then it kills everywhere, in the same way, and all the time, and every study result should either be consistent with that hypothesis or be explained away as flawed or faulty... ...the NEJM Study as it, for example, lacks information on the cause of death for any individual in the Medicare population, relies entirely on guesstimated exposure data, and fails to consider confounding factors such as smoking, socioeconomic status and any of the other myriad potential competing risk factors for death.
