Mortality among people with airflow limitation according to the fixed ratio criterion but not the lower limit of normal criterion
Abstract
Background: remains unclear, and we explore it in this study. Methods: Participants were enrolled from the National Health and Nutrition Examination Survey (NHANES) (1988-1994 and 2007-2012 cycles).

Multivariable logistic regression was used to identify differences in chronic respiratory symptoms and comorbidities between the groups. The multivariable Cox proportional hazards model was used to analyze between-group differences in all-cause mortality. Results: group (adjusted HR 1.34, 95% CI: 1.24-1.45, P
