Figure 3. Comparison of patient‐oriented composite outcome between preserved or depressed resistive reserve ratio, among high fractional flow reserve or high coronary flow reserve population with deferred revascularization.

The cumulative incidence of patient‐oriented composite outcome at 5 years is compared between preserved (≥3.5) and depressed resistive reserve ratio (<3.5) in subgroup of (A) high fractional flow reserve (>0.80) or (B) high coronary flow reserve (>2.0) among patients with deferred revascularization. CFR indicates coronary flow reserve; FFR, fractional flow reserve; HR, hazard ratio; and RRR, resistive reserve ratio.
