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

STUDY

objectivesObstructive sleep apnea (OSA) is associated with an increasing risk of cognitive impairment, but traditional hypoxic indicators can not accurately identify cognitive impairment. This study aimed to assess a new indicator, hypoxic burden, in cognitive impairment in OSA.

methodsA total of 116 patients with OSA were enrolled in this study. Daytime sleepiness and cognition were assessed using the Epworth Sleepiness Scales and Montreal Cognitive Assessment (MoCA), respectively. All participants underwent polysomnography (PSG). The hypoxic burden was derived from PSG and calculated according to a specific algorithm. All the participants were divided into two groups. Seventy-seven were OSA with mild cognitive impairment (OSA + MCI), and 39 were OSA without mild cognitive impairment (OSA-MCI). The relationship between hypoxic burden and cognitive impairment was analyzed by establishing a series of logistic regression models.

resultsHypoxic burden was higher in OSA + MCI group compared with OSA-MCI group, while there was no significance found for the apnea-hypopnea index between the two groups. After adjusting for various confounders, patients with OSA who had a higher total hypoxic burden and rapid eye movement-hypoxic burden in the fourth quartile were found to have an increased risk of MCI compared to those in the first quartile. The adjusted ORs were 7.69 (95% CI, 1.15 to 51.55) and 8.87 (95% CI, 1.22 to 64.34), respectively. However, There was no significant association between the other traditional hypoxic parameters and cognitive function after adjusting for various confounders.

conclusionsCompared to the conventional hypoxic parameter, a higher hypoxic burden is associated with cognition and may be an important indicator for assessing MCI in OSA.
