Impact of carotid tortuosity on outcome after endovascular thrombectomy.
Article in Neurological sciences : official journal of the Italian Neurological Society and of the Italian Society of Clinical Neurophysiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 1 of them a synthesis that pooled 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.
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
objectivesEndovascular thrombectomy (EVT) is efficacious in patients with large vessel occlusion stroke (LVO). We explored whether internal carotid (ICA) tortuosity increases the technical difficulty of EVT thereby lowering the chances of successful recanalization and favorable outcomes. PATIENTS AND
methodsConsecutive patients with LVO and patent ICAs who underwent EVT were included. Carotid tortuosity was determined on pre-EVT CTA and classified by raters blinded to outcomes into: type 1-straight ICA trunk and type 2-severe tortuosity potentially impeding adequate catheter placement. Thrombolysis in cerebral infarction (TICI) 2b-3 was considered successful recanalization, and 90-day-modified Rankin Scale ≤ 2 was considered favorable functional outcome.
resultsAmong 302 patients (mean age 70 ± 15, median NIHSS 17), 53% had type 1, and 47% type 2 tortuosity. Overall, 85% had successful recanalization. Patients with type 2 tortuosity were significantly older (p < 0.0001) and less frequently achieved successful recanalization (80% vs. 90%; p = 0.019) but had similar outcomes compared with those without tortuosity. On regression analysis, marked tortuosity was associated with lower chances of successful recanalization (OR 0.43 95% CI 0.20-0.92) but had no effect on clinical outcomes.
conclusionsCarotid tortuosity does not appear to impact the likelihood of favorable functional outcome but may influence recanalization.
