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
objectivesTo investigate the relationship between hematocrit (HCT) and low resting oxygen saturation in Tibetan plateau population.
methodsThis retrospec-tive cohort study included 3075 Tibetan adult inpatients who underwent elective non-cardiac, non-thoracic surgery at Tibet Autonomous Region People's Hospital between January 2023 and October 2024. Multivariate logistic regression was used to assess the association between HCT and low resting oxygen saturation (SpO
resultsMultivariate logistic regression analysis showed that elevated HCT was an independent risk factor for low oxygen saturation in the patients. For every 5-percentage-point increase in HCT, the risk of low oxygen saturation increased by 12% (
conclusionsThere is a U-shaped association between HCT and low resting oxygen saturation in the Tibetan plateau population. An HCT level exceeding the population-specific threshold suggests that the adaptive erythropoietic response to high-altitude hypoxia may transition from being compensatory to potentially detrimental.
