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
Background: Obstructive sleep apnoea (OSA) is linked to cardiovascular disease (CVD). The obstructive apnoea-hypopnoea index (oAHI) used for diagnosing and grading OSA has limitations in predicting CVD. The present study assessed and compared the association between nocturnal hypoxaemia parameters and left ventricular hypertrophy (LVH). Methods: A cross-sectional study was conducted on 187 consecutive adult outpatients diagnosed with OSA after home cardiorespiratory polygraphy. Blood pressure control was tested with ambulatory blood pressure monitoring. A standard transthoracic cardiac ultrasound examination assessed LVH. Oximetry parameters were grouped into a single parameter (Oxy-score) using factor analysis (a higher Oxy-score indicating better nocturnal oxygenation), which was tested for association with LVH. Results: The mean age was 60±12 years, with 75% male sex and 94% overweight/obese. The prevalence of arterial hypertension and LVH was 92% and 75%, respectively. The prevalence of severe OSA was 44%, with a mean oAHI of 32±19. Patients with LVH had significantly higher oAHI (34±19 Conclusion: Nocturnal oximetry parameters, grouped into a single parameter as a proxy of the global hypoxic burden, proved to be a better and independent predictor of LVH than oAHI, supporting the pivotal relevance of oximetry parameters beyond oAHI in patients with OSA.
