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

introductionObstructive sleep apnea (OSA) is a potential risk factor for cognitive impairment and dementia; however, its contribution in midlife and interactions with APOE ε4 remain unclear.

methodsParticipants were 2795 cognitively unimpaired, middle-aged adults enrolled in the Healthy Brain Project. OSA status was determined by self-report. Cognition was assessed using the Cogstate Brief Battery, and dementia risk using the Cardiovascular Risk Factors, Ageing, and Incidence of Dementia (CAIDE) score.

resultsParticipants with OSA demonstrated poorer memory than those without OSA, although this association was attenuated after adjusting for vascular risk. Individuals with OSA (with or without APOE ε4) had significantly higher CAIDE scores than those with neither risk factor. APOE ε4 did not moderate OSA-cognition associations. DISCUSSION: OSA may be associated with poorer memory and greater dementia risk, irrespective of APOE ε4 carriage. These findings highlight the need for early OSA screening to identify individuals at elevated dementia risk.
