Spirometry reference values for an andean high-altitude population.

Unlabelled: We compared the spirometric values of people living at High Altitude at the Andean Plateau with those predicted for lowland population.

Rationale: Spirometry reference values are not yet available for the millions of people living at high altitude in the Andean High Plateau.

Objective: To obtain spirometric prediction equations from a healthy subset of adults living in Argentina at 3440m above sea level.
