Results of Multivariate Linear Regression Model for CFR.

	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

Dependent Variable: Log₂ transformed CFR post Sildenafil

Independent Variable: Baseline log₂ transformed CFR

Covariates: Age*Baseline log₂ transformed CFR, HR*SBP at baseline

R-Square of Model: 0.50

Results: Baseline CFR is significant after adjusting for other baseline potential risk factors.
