Figure 4. Association of resistive reserve ratio with estimated risk of patient‐oriented composite outcome at 5 years among patients with deferred revascularization.

The non‐linear relationship between resistive reserve ratio and the estimated risk of patient‐oriented composite outcome at 5 years was plotted after adjustment with (A) percent diameter stenosis (%DS), (B) fractional flow reserve, or (C) multivariable adjustment. Adjusted covariates in the multivariable model are age, sex, hypertension, diabetes mellitus, hyperlipidemia, acute coronary syndrome, multivessel disease, fractional flow reserve, and % diameter stenosis. %DS indicates percent diameter stenosis; FFR, fractional flow reserve; and RRR, resistive reserve ratio.
