^aLogistic regression was used to determine exposure-disease associations
^bAnalytic sample size = 18,206 enrollees for all diseases
^cSPARCS data used for calculations included both IP and ED visits
^dRegressions controlled for gender, race, age at 9/11, and education
^eSR Self-report
^fCI Confidence interval
^gSelf-report-SPARCS odds ratio pairs in red are statistically significantly different
