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
objectiveTo investigate the complex association between hemoglobin levels and resting pulse oxygen saturation (SpO
methodsThis cross-sectional study enrolled adult inpatients from People's Hospital of Xizang Autonomous Region (altitude: 3 650 m) between January 2023 and October 2024. To rigorously evaluate the relationship between hemoglobin and resting SpO
resultsA total of 3 083 inpatients were enrolled in the final analysis, comprising 1 450 males and 1 633 females. The restricted cubic spline analysis revealed a significant non-linear relationship between hemoglobin levels and SpO
conclusionThis study establishes specific hemoglobin thresholds for oxygenation status in hospitalized patients at high altitude: 15.482 g/dL for females and 17.288 g/dL for males. Beyond these cut-off values, further increases in hemoglobin are associated with a deterioration in SpO
