Prevalence ratios and 95% CIs from GEE models for odors from livestock, liquid TSS, and cake TSS for North Carolina residents (n=430) who participated in a study of odors from TSS and livestock and self-reported health, 2010

^aResidents of the comparison areas were the referent group for none or faint and moderate/strong/very strong TSS odor.

^bResidents who reported no or faint livestock odor were the referent group for moderate/strong/very strong livestock odor.

^cPR adjusted for age, race, gender, education, smoking, passive smoking, agricultural chemical odors, and odors from burning.

^dSkin ulcer was also in this factor group, but the model for this symptom did not converge due to the small number of cases.

^ePresent if ever reported in the past six months

CI = confidence interval

GEE = general estimating equation

TSS = treated sewage sludge

PR = prevalence ratio
