Factors determining the therapeutic level of positive airway pressure in patients with obstructive sleep apnea syndrome.

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
Objectives: In daily practice, we encounter with obstructive sleep apnoea syndrome (OSAS) patients who require different levels of positive airway pressure (PAP) despite having a similar apnoea-hypopnea index (AHI). We aimed to determine the parameters contributing to the determination of the therapeutic level of PAP. Methods: Data on 548 patients who underwent polysomnography and PAP titration were analysed retrospectively. Patients were divided into groups according to OSAS severity (mild, moderate, and severe) and the mean pressure in each group was determined, after which patients were further divided into those who required a PAP below the mean and those who required a PAP above the mean. Results: The mean optimal PAP level in the mild, moderate, and severe OSAS groups was 7.4 ± 2.3, 8.6 ± 2.4, and 9.8 ± 2.9 cm H Conclusion: A longer apnoea duration and a higher supine AHI are associated with a higher PAP level in patients with moderate and severe OSAS.
