Results of logistic regression analysis assessing risk of cause-specific mortality associated with different CAFOs exposure: Odds ratios (95% confidence intervals) comparing risk in CAFOs exposure group to no exposure group, using different buffer sizes to assess exposure.

CAFOs exposure	Cause of death
	Cardiovascular	Respiratory	Asthma	Anemia	Kidney
Presence of CAFOs within each buffer
5 km	1.022 (1.011, 1.032)	0.988 (0.972, 1.003)	1.037 (0.914, 1.175)	1.066 (0.916, 1.241)	1.020 (0.988, 1.053)

CAFOs exposure based on the number of CAFOs within a 15 km buffer
Low	1.014 (1.002, 1.025)	1.017 (1.000, 1.033)	0.996 (0.865, 1.147)	0.914 (0.775, 1.077)	0.984 (0.951, 1.018)
Medium	1.044 (1.033, 1.055)	1.002 (0.986, 1.018)	1.043 (0.910, 1.195)	0.988 (0.843, 1.157)	1.021 (0.988, 1.055)
High	1.060 (1.047, 1.073)	1.000 (0.981, 1.018)	1.005 (0.863, 1.171)	1.203 (1.006, 1.438)	1.073 (1.033, 1.114)

Note: CAFO category was based on the presence of CAFOs within each buffer around residence or tertiles group (low, medium, and high) based on the number of CAFOs within a 15 km buffer. Models were adjusted for sex, age, race/ethnicity, education, median household income, urbanicity, year, season, and region.

Each cause of death was analyzed separately.
