Results of Multivariate Linear Regression Model for Coronary Flow Reserve^a

	Beta (SE)	P Value
Intercept	1.03 (0.22)	0.0002
Baseline log2‐transformed CFR	0.61 (0.17)	0.0025
Age × baseline log2 transformed CFR	0.23 (0.13)	0.0945
HR × SBP at baseline	2.98 (1.27)	0.0303

Abbreviations: CFR, coronary flow reserve; HR, heart rate; SBP, systolic blood pressure; SE, standard error.

^aDependent variable: log₂‐transformed CFR post‐sildenafil; independent variable: baseline log₂‐transformed CFR; covariates: age × baseline log₂‐transformed CFR, HR × SBP at baseline; R² of model: 0.50; results: Baseline CFR is significant after adjusting for other baseline potential risk factors.
