Abstract

Background: This study aims to provide mild chronic obstructive pulmonary disease and all cause mortality are related. Methods: Following PRISMA 2020 guidelines, this systematic review focused exclusively on full-text articles published in English between 2014 and 2024. Result: The study conducted a comprehensive review of over 100 publications sourced from reputable databases, including ScienceDirect, SagePub, and PubMed. Following an initial screening, five publications were identified as warranting more in-depth analysis. Consequently, a thorough review of these selected studies was performed to ensure a detailed and rigorous evaluation. Conclusion: When compared to normal spirometry, moderate COPD is linked to higher death from all causes and mortality from respiratory diseases. To find out if early treatment and intervention are helpful in mild COPD, more research is needed.
