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
Sleep-disordered breathing is common among patients with heart failure with preserved ejection fraction (HFpEF), and might impact their quality of life due to nighttime hypoxemia and awakenings. However, the factors contributing to deterioration in quality of life remain unclear. This study investigated the factors associated with quality of life deterioration in patients with HFpEF and sleep-disordered breathing. This prospective cross-sectional study included inpatients with HFpEF (left ventricular ejection fraction of ≥ 50%). Sleep-disordered breathing and quality of life were evaluated using polysomnography and the Short Form-8 Health Survey, respectively. The patients were grouped based on thei median physical and mental component summary Short Form-8 Health Survey scores. Among the 31 patients with HFpEF (aged 73.7 ± 10.9 years; 67.7% women; left ventricular ejection fraction, 65.3% ± 8.1%), the median apnea-hypopnea index was 11.5 per hour. Although no differences in parameters related to sleep-disordered breathing were found among the physical component summary-stratified groups, the low mental component summary group exhibited significantly lower nadir oxygen saturation than those exhibited by the high mental component summary group (84.3 ± 5.7% vs. 88.5 ± 3.9%; p = 0.02); this difference remained significant even when adjusted for potential confounders (β = 0.43; p = 0.02). Nocturnal hypoxemia may be a contributing factor to the decline in the mental health aspect of quality of life in patients with HFpEF. Thus, clinicians should consider hypoxemia when managing HFpEF and sleep-disordered breathing.
