Abstract
In fully adjusted logistic regression models, patients with higher CFR had lower risk of frailty; [OR for high CFR, 95% CI was 0.58 (0.43 - 0.77)] and [(OR per 1 unit of CFR increase, 95% CI was 0.63 (0.54 - 0.75)], p<0.001 Conclusions: Our Analysis suggest that frailty is independently associated with low CFR.
