Comparison of the lower limit of normal to the fixed ratio method for the diagnosis of airflow obstruction at high altitudes: a large cross-sectional survey of subjects living between 3000–4700 m above sea level

BACKGROUND: There is no general agreement on the preferential use of a fixed ratio (FR) of forced expiratory volume in 1 s (FEV(1))/forced vital capacity (FVC) < 0.7 vs. the lower limit of normal (LLN) of FEV(1)/FVC to define airflow obstruction. Determining the impact of these different cut-off...
