Clinical and physiological stability and readmission rates. A, Kaplan-Meier plot of time to first readmission within 30 days after hospitalization due to acute exacerbations of COPD (AECOPD) according to clinical stability at discharge. B, Kaplan-Meier plot of time to first readmission within 30 days after hospitalization due to AECOPD according to physiological stability at discharge. C, Kaplan-Meier plot of time to first readmission within 30 days following hospitalization due to AECOPD according to physiological and clinical stability at discharge. D, Forest plot showing ORs for readmission within 30 days after discharge according to physiological and clinical stability at discharge.
