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

purposeThe aim of this study was to accurately determine the prevalence of obstructive sleep apnoea (OSA) in patients with epilepsy (PWE) and to evaluate the efficacy of seizure control after treating OSA.

methodsArticles were identified through a search of both MEDLINE and Embase. The articles were collected and data were extracted independently by two authors. OSA was described using the following terms: Apnoea/hypopnoea index (AHI) and respiratory disturbance index (RDI). The variables were calculated using DerSimonian and Laird's random-effects model and odds ratio (OR).

resultsThe prevalence of mild-to-severe OSA in PWE was determined to be 33.4 % (95 % CI 20.8-46.1 %), and PWE are more susceptible to OSA as compared to healthy controls (OR 2.36; 95 % CI 1.33-4.18). Males were shown to be more susceptible to OSA than females (OR 3.00; 95 % CI 2.25-3.99). The results also indicated that the prevalence of OSA in patients with refractory epilepsy is not higher than the prevalence of OSA in PWE overall (17.5 vs 33.4 %). The prevalence of OSA was not found to be significantly different for different seizure types or in the number of antiepileptic drugs (AEDs). Patients that had been treated with continuous positive airway pressure (CPAP) were shown to have better seizure control than those untreated (OR 5.26; 95 % CI 2.04-13.5).

conclusionsThe prevalence of OSA in PWE is higher than in the general population. Additionally, the results of our study suggest that CPAP treatment results in a reduction of seizures.
