Predictive tools for nocturnal respiratory failure in patients with moderate and severe OSAS.

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
purposeThe impact of obstructive sleep apnea syndrome (OSAS) in terms of mortality, morbidity, and quality of life has been well established. Phenotyping OSAS is essential in order to make the best therapeutic choice. A particular subset of patients with OSAS shows nocturnal respiratory failure, defined by a nighttime oxygen saturation <90% in more than 30% of the total sleep time (TST90). The aim of this study was to identify possible predictive factors for nighttime respiratory failure (NRF) in patients with OSAS.
methodsIn this retrospective study, patients with suspected OSAS who underwent a sleep study were enrolled. Of 116 patients with moderate/severe OSAS who met the inclusion criteria, 67 also had nocturnal respiratory failure. We compared clinical, anthropometric, and laboratory data in patients with OSAS vs. OSAS and nocturnal respiratory failure.
resultsPatients with OSAS and nocturnal respiratory failure were more frequently female, had a higher BMI, lower daytime oxygen partial pressure (PaO2) in arterial blood, higher Apnea Hypopnea Index (AHI), and a lower number of sleep hours per night. Chronic obstructive pulmonary disease (COPD) was more diagnosed in the group of patients with nocturnal respiratory failure. A lower number of total sleep hours, lower daytime PaO2, lower AHI, increased oxygen desaturation index (ODI), and the presence of a diagnosed COPD were all found to increase the risk of having nocturnal respiratory failure.
conclusionCOPD, AHI, ODI, daytime PaO2, and total sleep hours are the main predictors for NRF in patients with moderate and severe OSAS.
