Preoperative Neurological Changes on Outcomes in Large-Vessel Occlusion Due to Intracranial Atherosclerotic Disease.

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.
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
BACKGROUND AND
objectivesWe aimed to clarify the association between neurological deterioration pre-endovascular therapy (EVT) and outcome in patients with large-vessel occlusion due to intracranial atherosclerotic disease (ICAD-LVO) undergoing EVT.
methodsConsecutive patients with acute ischemic stroke due to ICAD-LVO within 24 h of onset who underwent EVT were enrolled in the Japanese multicenter registry from 2017 to 2019. Patients were grouped according to neurological severity transition as follows: mild symptoms (baseline National Institutes of Health Stroke Scale [NIHSS] score <6 and NIHSS score pre-EVT <6), symptom deterioration (baseline NIHSS score <6 and NIHSS score pre-EVT ≥6), and severe symptoms (baseline NIHSS score ≥6 and NIHSS score pre-EVT ≥6). Outcomes included favorable outcomes (modified Rankin Scale [mRS] score of 0-2 at 90 days), ordinal mRS shift, and symptomatic intracranial hemorrhage. Multivariable logistic regression assessed the association of outcomes with the transition of neurological severity by calculating odds ratios and 95% CIs, with mild symptoms as reference.
resultsIn total, 480 patients with acute ICAD-LVO who underwent EVT (150 women [31.2%]; median age, 72 years IQR, 66-80) and had median baseline NIHSS score 12 (IQR, 6-20) were analyzed. Patients with symptom deterioration (n = 34) and severe symptoms (n = 375) had lower favorable outcomes (deterioration 38.2% vs mild 62.9%; adjusted odds ratio 0.30, 95% CI 0.09-0.97, severe 35.3%; 0.47, 0.33-0.65) and a significant mRS shift (deterioration vs mild; 3.63, 1.46-9.03, severe; 2.27, 1.74-2.96) than those with mild symptoms (n = 71). Symptomatic intracranial hemorrhage rates did not differ (mild 0%; deterioration 0%; severe 1.9%).
conclusionPatients with ICAD-LVO who experienced worsening symptoms were less likely to achieve favorable outcomes after EVT than those with mild symptoms. Early identification of neurological deterioration and EVT intervention may improve outcomes in these patients.
