Propensity Score Analysis of the Association between Chronic Obstructive Lung Disease and Stroke Outcome: Thailand's National Database.

Introduction: The impact of coexisting chronic obstructive lung disease (COPD) in patients with stroke remains unclear. This study aims to investigate the effect of COPD on survival and hospital outcomes among stroke patients.

Methods: The outcomes of patients with stroke between fiscal years 2005 and 2017 from Thailand's Universal Coverage Scheme database were compared between COPD and non-COPD patients using propensity score matching and flexible parametric survival model.
