Nonlinear association between admission oxygen partial pressure and in-hospital and one-year all-cause mortality in patients with coronavirus disease pneumonia: A retrospective cohort study.

ABSTRACT:

Background

This study investigated the correlation between admission partial pressure of arterial oxygen (PaO₂) levels and both in-hospital mortality and 1-year all-cause mortality among patients diagnosed with coronavirus disease (COVID-19) pneumonia.

Methods

This retrospective cohort study included patients with COVID-19 pneumonia admitted to the First Hospital of Jinzhou Medical University. Restricted cubic spline regression and logistic regression analyses were employed to assess the relation between PaO₂ levels and the risk of in-hospital mortality and all-cause mortality within 1 year. Subgroup analyses were performed, stratified by age, sex, presence of cardiac disease, diabetes, hypertension, whether supplemental oxygen was provided during arter
