  1. GERD: gastroesophageal reflux disease
  2. PTSD: posttraumatic stress disorder
  3. aBurden estimates are rounded to the nearest integer
  4. bMidpoint estimate is the product of the percent ill among list-identified persons and the total population exposed. Lower bound estimate adjusts for the possibility that even among listed persons, those ill were 50% more likely to enroll in the WTCHR. The lower bound estimate is the product of the total population exposed and the ratio of A to B, where (A) is the number of list-identified persons who were ill and (B) is the sum of the number of list-identified persons who were healthy × 1.5 and the number of list-identified persons who were ill. Upper bound estimate is the product of the percent ill among self-identified persons and the total population exposed
  5. cEstimates from Murphy J, Brackbill RM, Thalji L, et al. Measuring and maximizing coverage in the World Trade Center Health Registry. Stat Med 2007;26:1688–1701
  6. dConditions included were asthma, GERD, PTSD, and depression
