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

objectivesObstructive sleep apnea (OSA) is a common sleep disorder that has several health hazards, including cognitive dysfunction. Studies have thus far primarily focussed on the prevalence of cognitive impairment in patients diagnosed with OSA at sleep clinics. The present study aims to investigate the prevalence of OSA at an outpatient memory clinic.

methodsA dataset of patients who visited our memory clinic in the period from June 2015 to September 2019 was retrospectively examined for the presence of OSA. The primary outcome measure was the prevalence of OSA, subdivided into three cognitive syndrome diagnosis groups: subjective cognitive complaints (SCC), mild cognitive impairment and dementia. Secondary outcome measures included age, education level, body mass index, substance use, depression and OSA criteria.

resultsOf the 885 patients included in this study, 153 patients had already been or were diagnosed with OSA (17.3%). The percentage of OSA in the SCC group was significantly higher compared with the dementia group (26.7% vs 8.0%; OR 3.83 [95%CI 2.43-5.99]). Age differed significantly between the SCC group and the dementia group: 63.5 vs 71.5 years (7.6 ± 1.810;

conclusionsPrevalence of OSA at our outpatient memory clinic is generally high. Especially in patients with SCC. We would therefore advocate screening for OSA at memory clinics.
