Association Between Noninvasive Test Type and Positive Test Results in Women and in Men

	Positive Test Rate, No. of Positive Tests/Sample Size (%)		CTA versus Stress Test Unadjusted*		CTA versus Stress Test Adjusted†
Model/Comparison	CTA	Stress Test	Odds Ratio (95% CI)	P-value	Odds Ratio (95% CI)	P-value
Interaction between randomized arm and sex			---	< 0.001	---	< 0.001
CTA versus stress test in women	184/2332 (7.89%)	274/2388 (11.47%)	0.66 (0.54 - 0.80)	< 0.001	0.67 (0.55 - 0.82)	< 0.001
CTA versus stress test in men	350/2168 (16.14%)	290/2078 (13.96%)	1.19 (1.00 - 1.41)	0.047	1.23 (1.04 - 1.47)	0.019

^*Unadjusted models contained sex, randomized testing arm, and interaction term.

^†Adjusted for age, race, body mass index, coronary artery disease (CAD) equivalent, Framingham risk score (12), ASCVD (13), Diamond and Forrester (14), hypertension, dyslipidemia, diabetes, family history of premature CAD, sedentary lifestyle, smoking, typicality of chest pain, and physician's estimation of likelihood of significant CAD.

CTA = computed tomographic angiography; NIT = noninvasive test.
