Investigating the Differences in Polysomnography Results Evaluated According to the Recommended and Alternative Hypopnea Criteria Utilized in the Evaluation of Polysomnography.

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
objectiveThe criteria of hypopnea recommended by the American Academy of Sleep Medicine until 2012 was 3% desaturation and 50% decline in the signal amplitude. The recommended and alternative criteria for hypopnea were determined as 3% desaturation accompanied by a 30% decline in the signal amplitude and 4% desaturation accompanied by a 30% decline in the amplitude by the 2013 update of the guideline was published by the American Academy of Sleep Medicine in 2012. The objective of our study was to investigate to what degree scoring of hypopneas has great importance in the diagnosis and severity grading of obstructive sleep apnea syndrome according to different criteria. MATERIAL AND
methodsThe present study was designed as a retrospective study in which the results of the polysomnography of 62 patients were recorded after evaluation according to 3 different hypopnea criteria. Criteria 1, criteria 2, and criteria 3 were accepted as a 3% drop in SaO2 accompanied by a 30% decline in the amplitude, as a 4% drop in SaO2 accompanied by a 30% decline in the amplitude, and as a 3% drop in SaO2 accompanied with a 50% decline in the amplitude, respectively.
resultsStatistically significant differences were determined between criteria 1 and criteria 2, criteria 1 and criteria 3, and criteria 2 and criteria 3 regarding the numbers of hypopneas.
conclusionFor the same polysomnography, evaluations with different accepted hypopnea criteria cause different polysomnography results.
