Spirometry at different Latin American altitudes: a Global Lung Function Initiative project.
Article in ERJ open research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Aim: Approximately 20% of people in Latin America live more than 2500 m above sea level. In this ethnically and socioeconomically diverse population, it is challenging to differentiate the effects of altitude from population differences in lung function. The aim of the present study was to quantify the contribution of altitude on the variability in lung function measured by spirometry in Latin America. Methods: Data from healthy individuals living in nine cities across Latin America (from sea level to >2500 m above sea level) were collated. Results: A total 4480 subjects (3-94 years) were included. Average FEV Conclusion: For people living at altitude, existing approaches to interpreting spirometry measures may misclassify individuals.
