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

objectiveThis study investigated whether large ischemic lesions in the deep white matter (DWM) on pretreatment diffusion-weighted MRI (DWI) predict futile recanalization.

methodsConsecutive acute stroke patients with anterior circulation ischemia who underwent successful arterial recanalization with thrombolysis in cerebral infarction grade 2b or 3 were enrolled. A large DWI-DWM lesion was defined as a hyperintense lesion in the DWM on initial DWI, located mainly between the anterior and posterior horns of the lateral ventricle. The Alberta Stroke Program Early CT score on CT and DWI and stroke volume on initial DWI were recorded. Stroke severity was assessed using the National Institutes of Health Stroke Scale (NIHSS) score. Futile recanalization was defined as a 30-day modified Rankin scale score of 3-6 despite successful recanalization. Univariate and multivariate regression analyses were performed to identify predictors of futile recanalization.

resultsIn 35 of 46 patients (76%) with successful recanalization, futile recanalization was observed in 20 patients (57%). Patients with futile recanalization were older (median age 74 vs. 58 years; p = 0.053), had higher initial NIHSS scores (median 17 vs. 9; p = 0.042), and a higher prevalence of large DWI-DWM lesions (45 vs. 9%; p = 0.022). Logistic regression analysis showed that a large DWI-DWM lesion was an independent predictor of futile recanalization (OR 13.97; 95% CI 1.32-147.73; p = 0.028).

conclusionPatients with large preintervention DWI-DWM lesions may be poor candidates for endovascular therapy.
