This study aimed to compare how the Fried Frailty Phenotype (FFP) and Short Physical Performance Battery (SPPB) characterise frailty in people with stable COPD, including prevalence of and overlap in identification of frailty, disease and health characteristics of those identified as living with frailty, and predictive value in relation to survival time.Methods: Cohort study of people with stable COPD attending outpatient clinics. Agreement between frailty classifications was described using Cohen’s Kappa. Disease and health characteristics of frail versus not frail pa
