Evaluation of the performance of the reference equations for single-breath diffusing capacity of the lung for carbon monoxide (DLCOsb) in Latin American populations at different altitudes: A multicentre study
Although with wide limits of agreement for all models, Vázquez-García's equation shows the best performance in the interpretation of DLCOsb in Latin American populations residing at any altitude. Even with adjustments for altitude and Hb, the GLI model underestimates the predicted values of DLCOsb and could require an adjustment factor or inclusion of the altitude variable in the model's new version.
