Educational value of remote live-streamed training in endovascular thrombectomy: dose-response and mediation analysis.
Article in Journal of neurointerventional surgery, 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
backgroundRemote live-streamed training in endovascular thrombectomy (EVT) is a novel educational strategy. This study evaluated the dose-response relationship between training duration and clinical outcomes, and explored mediation pathways.
methodsIn a prospective cohort study, 1046 participants received remote EVT training, with 1010 completing follow-up. Locally Estimated Scatterplot Smoothing (LOESS) and segmented regression identified training thresholds. Participants were categorized into low (<25 hours), medium (25-70 hours), and high (>70 hours) training groups. Inverse probability of treatment weighting (IPTW) was adjusted for baseline differences. Mediation analysis examined the mechanisms of effect.
resultsA dose-response relationship was evident: outcome improvements accelerated after 25 hours and plateaued beyond 70 hours. After IPTW, patients treated by both medium and high training groups achieved significantly better 90-day outcomes compared with the low training group (medium vs low, adjusted β=1.54, 95% CI 0.94 to 2.15; high vs low, β=3.16, 95% CI 2.28 to 4.04, both P<0.001). Mediation analysis revealed that increased professional competency (25.0%), reduced recanalization time (32.8%), and higher recanalization rates (46.1%) partially explained the improved outcomes (all P<0.001). Sensitivity analyses supported these findings.
conclusionRemote live-streamed EVT training is significantly associated with improved 90-day functional outcomes. The greatest benefits were observed after 25 hours of training and diminishing returns beyond 70 hours. These gains are partly mediated by enhanced professional competency and improved recanalization outcomes, highlighting the importance of structured, high-quality remote training programs for optimizing neurointerventional care.
