Adjusted using hierarchical multivariate logistic regression models. Only statistically significant associations are shown. ORs>1 indicate a higher likelihood of a positive change in health outcome and ORs<1 indicate a lower likelihood of a positive change in health outcome.
↵* Refers to report of any one of the five illnesses included in this table.
FHLP, failed healthy living practice; PPB, persons per bedroom; RRR, relative risk ratios; SCS, Surveyor Condition Score; SFS, Surveyor Function Score.
ORs for which the CI excludes 1 are shown in bold.
