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

Obstructive sleep apnea syndrome (OSAS) is a prevalent condition caused by dynamic upper airway collapse during sleep. The pathological impact and consequences are due to chronic intermittent hypoxia (CIH). Hypoxia increases the expression of several inflammatory stress markers and endothelial dysfunction. Recent studies suggest that patients with a similar AHI but with severe nocturnal hypoxia using oximetric parameters, such as the lowest saturation of oxygen during the night (min SaO2), percentage of total sleep time with oxygen saturation < 90% (T90) or the oxygen desaturation index (ODI-3%), commonly reported during the sleep study, are indicative of the increased expression of inflammatory markers due to severe nocturnal hypoxia and CIH during the night compared to subjects with moderate-severe OSAS without severe nocturnal hypoxia. The aim of this review is to describe physiological pathways involved in OSAS and their clinical consequences, focused in CIH and oximetric parameters showed in sleep study and their potential utility as inflammatory markers.
