Exercise capacity of patients with obstructive sleep apnea at moderate to high altitude.
Article in Sleep & breathing = Schlaf & Atmung, 2026. 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
backgroundIt remains unknown to what extent exercise capacity is diminished at moderate to high altitudes in patients with obstructive sleep apnea (OSA). PURPOSE: The primary aim was to compare peak oxygen uptake per kilogram body weight (VO
methodsThis prospective study enrolled 38 OSA patients (AHI ≥ 5 events/h) and 36 healthy controls from Kunming, Yunnan Province, China (study site altitude: ~1,900 m; participants' residence altitude range: 1,800-2,800 m above sea level). All participants underwent overnight polysomnography and symptom-limited CPET using a cycle ergometer ramp protocol. Both groups were subgrouped by apnea-hypopnea index (AHI) severity and by lowest oxygen saturation (LSpO
resultsAfter adjustment for BMI, the OSA group exhibited significantly lower VO
conclusionsOSA patients at moderate-to-high altitude show reduced exercise capacity (lower VO
