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 purpose of the study was to assess polysomnographic indicators of increased mortality risk in patients with stroke or a transient ischemic attack (TIA).

methodsWe performed polysomnographies in 63 acute stroke/TIA patients. Mortality data were collected from a national database after a 19-37-month follow-up period.

resultsOf the 57 stroke and 6 TIA patients, 9 stroke patients died during follow-up. All nine had moderate or severe sleep-related breathing disorders (SRBDs). Binarily divided, the group with the highest apnea hypopnea index (AHI) had an almost 10-fold higher mortality risk (hazard ratio (HR) 9.71; 95 % confidence interval (CI) 1.20-78.29; p = 0.033) compared to the patients with the lowest AHI. The patients with the longest versus shortest nocturnal wake time had a higher mortality (HR 8.78; 95 % CI 1.1-71.8; p = 0.0428). Lung disease increased mortality (HR 9.92; 95 % CI 2.00-49.23; p = 0.005), and there was a trend toward a higher mortality risk with atrial fibrillation/flutter (HR 3.63; 95 % CI 0.97-13.51; p = 0.055).

conclusionsIn stroke patients, the AHI and nocturnal wake time are indicators of increased mortality risk. SRBDs in stroke patients should receive increased attention.
