LiVE-STROKE: live video from bystander to the medical dispatcher in potential stroke cases.
Article in Scandinavian journal of trauma, resuscitation and emergency medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundIdentification of stroke during an emergency call remains challenging. We aimed to explore performed stroke examination with prehospital live video transmission during an emergency call from a bystander's smartphone to the medical dispatcher.
methodsSince 2019, the Emergency Medical Services (EMS) in Copenhagen, consisting of the Emergency Medical Coordination Centre (EMCC) and the Out-of-Hours Health Service (OOHS), have enabled medical dispatchers to add live video to emergency calls. Dispatchers are registered nurses or paramedics. Live video is initiated via text message link sent to the caller's smartphone. We included all cases where the dispatcher added live video to the emergency call and stroke was suspected or later identified according to the Danish Stroke Registry. The video-recorded on-site stroke examinations were retrospectively analyzed. No specific guidance for video-based stroke examination was in place.
resultsA successful live video transmission was achieved in 550 potential stroke cases, where 52% were correctly examined for facial paresis and 16% for both facial and extremities paresis. In six patients, hemiparesis was observed without an examination. The group with 'considered stroke' had the highest amount of examined cases. Dispatchers suspected stroke in 450 cases, and stroke was confirmed in 16% (n = 73). Stroke was diagnosed in 126 cases and was not suspected in 46% of these cases (missed stroke n = 63, TIA n = 10). Patients with missed stroke had significantly less accurate examinations and more often hemorrhagic stroke, compared to patients with confirmed stroke.
conclusionVideo is not routinely used for stroke assessment during emergency calls, and only a small number of cases are sufficiently examined for stroke with video. Implementation of a structured protocol for live video guided stroke examinations during emergency calls could be beneficial but best practice is still unknown.
