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

objectiveCurrently accepted guidelines categorize obstructive sleep apnea (OSA) severity according to the Apnea-Hypopnea Index (AHI). However, it is unclear how to best define OSA severity. The present study sought to evaluate the concurrent validity of the widely accepted AHI by correlating it with various oxygen saturation (SpO

methodsThe study utilized the data of a previous survey concerning the prevalence of OSA among a middle-aged Saudi population (

resultsThe study found that there were correlations between the standard OSA severity based on AHI severity classification and different SpO

conclusionOur findings support the clinical reliability of the currently used standard classification of OSA severity based on the AHI.
