1 · What the graph read from it

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.

2 · The registry

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

In this study, the association between obstructive sleep apnea severity and the parapharyngeal fat pad volume is examined in a population-based sample. We included 680 participants who underwent standardised overnight polysomnography between 2008 and 2012 as part of the Study of Health in Pomerania in a sleep laboratory in Greifswald, Germany. The apnea-hypopnea index was used as a marker of obstructive sleep apnea severity and the parapharyngeal fat pad volume, as our variable of interest, was analysed based on Magnetic Resonance Imaging data by automated image segmentation. We performed an ordinal logistic regression analysis to test the effect of parapharyngeal fat pad volume on apnea-hypopnea index, controlling for body-mass index as a confounder. The results indicated that greater parapharyngeal fat volume was associated with a higher apnea-hypopnea index in an unadjusted analysis. After adjustment for body-mass index, this association was no longer significant. An exploratory body-mass index-stratified analysis suggested that the association between parapharyngeal fat volume and apnea-hypopnea index may be present primarily in non-obese individuals. These findings highlight the importance of considering body-mass index as a measure for overall obesity when evaluating the specific role of parapharyngeal fat in obstructive sleep apnea.
