Testing a Conceptual Model of Physiologic Reserve, Intrinsic Capacity, and Physical Resilience in Hospitalized Older Patients: A Structural Equation Modelling

The relationship among physiologic reserve, intrinsic capacity, and physical resilience has not been examined, and a conceptual model that includes these key determinants of healthy ageing is needed. This study aimed to test a conceptual model using real-world data to determine the relationships among physiologic reserve, intrinsic capacity, physical resilience, and clinical outcomes.
