Gaps in the access to endovascular thrombectomy for acute ischaemic stroke: estimating neurointerventional training needs and modelling implementation impact based on current thrombectomy indicators.
Article in European stroke journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionEndovascular therapy (EVT) has become an increasingly important part of acute stroke management. However, the lack of trained neurointerventionalists represents a key barrier in expanding availability of EVT in Europe. This project aimed to investigate the association between the number of neurointerventionalists and overall EVT rates. PATIENTS AND
methodsA cross-sectional analysis was conducted using publicly available data from the Global Burden of Disease Report 2021 and the Stroke Action Plan for Europe (Stroke Service Tracker). Data on the number of neurointerventionalists across 35 European countries were surveyed through a structured survey distributed via the Resident and Research Fellow Section (RRFS) of the European Academy of Neurology (EAN). Correlation analyses were performed to estimate the association between neurointerventionalist density per served population, EVT rates and stroke-related mortality and morbidity.
resultsSurvey response rate was 71% (25/35 countries). The proportion of acute ischaemic stroke patients treated with EVT ranged from 0.05% to 14.96% of people with ischaemic stroke, and the number of neurointerventionalists ranged from 9 to 137 per country and from 0.3 to 7.5 per million inhabitants. There was a positive correlation between the number of neurointerventionalists per population served and EVT rates (Spearman coefficient ρ = 0.507; 95% CI, 0.209-0.719). Greater availability of trained neurointerventionalists was moderately associated with lower national ischaemic-stroke mortality (ρ = -0.473; 95% CI, -0.746 to -0.065) and lower overall disability-adjusted life years (ρ = -0.444; 95% CI, -0.729 to -0.027). DISCUSSION AND
conclusionThe number of neurointerventionalists correlates positively with the annual volume of EVT across European countries; higher EVT rates were also associated with lower stroke-related mortality and disability; however, these associations are unadjusted for other important confounders and causality cannot be inferred. These data suggest an urgent need to increase neurointerventional capacity in Europe, for example, by expanding dedicated national training programmes and enhancing support from national and international professional societies.
