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

objectiveAmong patients assessed by the emergency medical service (EMS) and hospitalized with a final diagnosis of stroke, to describe delays, patient characteristics, actions taken and outcome in relation to the early recognition of stroke by the EMS clinician.

methodsPatients admitted to any of six stroke units in Region Västra Götaland, Sweden, with a final diagnosis of stroke from 1 January 2013 to 31 December 2015 were included. Data on follow-up were retrieved from the Swedish Stroke Register.

resultsIn all, 5467 patients were included. Stroke was recognized by the EMS clinician in 4396 cases (80.4%). The mean difference in the time from dialling 112 until arrival at the stroke unit was 556 min shorter when stroke was recognized, while the mean difference in the time from dialling 112 until a preliminary report from a computed tomography (CT) scan was 219 min shorter as compared with the patients in whom stroke was not recognized. After adjustment for age, sex, neurological deficits and coma, a lack of suspicion of stroke on EMS arrival was associated with an increased risk of death during three months of follow-up (odds ratio 1.66; 95% confidence interval 1.19-2.32; p = .003).

conclusionAmong patients with a stroke, more than 80% were recognized by the EMS clinician. Early recognition of stroke was associated with a markedly shorter time until arrival at the stroke unit and until the preliminary report of a CT scan. A lack of early stroke recognition was associated with an increased risk of death.
