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

backgroundPrevalence and contribution of intracranial and extracranial arterial stenosis to stroke risk were assessed prospectively in children and young adults with sickle cell disease.

methodsIn this cross-sectional study, children and young adults (mean = 19.4 years) with sickle cell disease underwent neurological examination, brain MRI, and magnetic resonance angiography of the head and neck. Two neuroradiologists independently recorded infarcts and arterial stenosis. Clinical features and stroke outcomes were compared between participants with and without stenosis and between children and young adults. Logistic regression analysis assessed the association of variables of interest with overt stroke and silent cerebral infarct.

resultsOf 167 participants (79 children and 88 young adults), 20 (12.0%) had intracranial stenosis, all in the anterior circulation, and nine had concurrent extracranial stenosis. No participants had isolated extracranial stenosis. Participants with intracranial stenosis were more likely than those without stenosis to have an overt stroke (70% vs 5%, P < 0.001) or silent cerebral infarct (95% vs 35%, P < 0.001). Logistic regression analysis indicated that intracranial stenosis was strongly associated with overt stroke when compared with participants with silent cerebral infarct alone and strongly associated with silent cerebral infarct when compared with participants with normal brain MRI; male sex and age were also significant predictors of silent cerebral infarct.

conclusionsIntracranial stenosis was strongly associated with both overt stroke and silent cerebral infarct; prevalence of intracranial stenosis was similar to prior estimates in sickle cell disease. Extracranial stenosis without concurrent intracranial stenosis did not occur and thus could not be evaluated as an independent risk factor for stroke.
