Gran altitud y prevalencia de la enfermedad pulmonar obstructiva crónica: ¿relación casual o causal? (original) (raw)

The study investigates the correlation between altitude and the prevalence of chronic obstructive pulmonary disease (COPD), given contradictory findings in previous research. It involves a large-scale assessment of patients over 40 years old across 27 cities in Mexico, demonstrating a negative correlation between altitude and COPD prevalence. Findings indicate higher rates of COPD in cities below 1,000 meters, with significant metrics showing a decrease in prevalence as altitude increases, suggesting altitude may influence COPD risk and severity.
