Estimated Effects on CMR Parameters Associated With a 20% Increase in IMR (mm Hg/s) Derived From Univariable Models

	r	Effect of IMR	95% CI	P
Univariable associations, early CMR (2 days)
Area at risk, %	0.29	1.07	0.39 to 1.76	0.003
Infarct size, %	0.45	1.84	1.12 to 2.56	<0.001
Myocardial salvage index, %	−0.41	−3.42	−4.93 to −1.92	<0.001
Microvascular obstruction, %	0.35	0.37	0.18 to 0.56	<0.001
Hemorrhage, %	0.43	0.28	0.17 to 0.40	<0.001
Left ventricular ejection fraction, %	−0.27	−0.80	−1.35 to −0.24	0.005
Univariable associations, late CMR (3 months)
Infarct size, %	0.34	1.13	0.48 to 1.79	<0.001
Myocardial salvage index, %	−0.31	−2.46	−4.01 to −0.92	0.002
Left ventricular ejection fraction, %	−0.27	−0.77	−1.34 to −0.20	0.009
