Adjusted Odds Ratios for Receiving CCATH Among Patients Who Reported Moderate to High Patient Decision Involvement Participation in Decision Making (vs No Involvement) Following Positive Cardiac Stress Testing

Model	Variables	Odds Ratio	95% CI	P value
Model 1	Patient Perceived Decision Involvement (PDI) Moderate to High PDI vs No PDI	1.9	1.4, 2.5	<.001
Model 2	PDI + Race (White vs Black)	1.9	1.4, 2.5	<.001
Model 3	PDI + Race + Sociodemographicsa	1.9	1.5, 2.6	<.001
Model 4	PDI + Race + Sociodemographics + Clinicalb Variables	1.9	1.4, 2.6	<.001
Model 5	PDI + Race + Sociodemographics + Clinical Variables + MD assessmentsc	1.5	1.1, 2.2	.02

^aSociodemographic variables included in regression analysis were income, education, and marital status.

^bClinical variables included in regression analysis were presence or absence of a history of hypertension, diabetes, angina, renal dysfunction, lung disease, congestive heart failure, prior revascularization, prior myocardial infarction, presence of angina symptoms, and whether the patient was on maximal medical treatment for CHD, derived from chart review.

^cMD assessments included likelihood of CHD and likely benefit of CCATH.
