Predictive value of motor-evoked potentials for upper limb functional outcomes in acute ischemic stroke.
Article in Annals of medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundStroke remains a leading cause of acquired physical disability globally, with upper limb motor impairment significantly affecting independence and quality of life. Currently, objective neurophysiological biomarkers are not routinely incorporated into stroke care. This study aimed to investigate the predictive value of MEPs for upper limb outcomes in acute ischemic stroke. PATIENTS AND
methodsThis prospective cohort study included 133 adults experiencing their first acute ischemic stroke. Within 10 days of onset, participants underwent Motor-evoked potential (MEP) testing via transcranial magnetic stimulation (TMS) and were categorized as MEP+ (with preserved responses) or MEP- (with absent responses). Outcome measures included the Fugl-Meyer Assessment (FMA), Barthel Index, and modified Rankin Scale (mRS), assessed at baseline and 90 days. Logistic regression models adjusted for age and baseline stroke severity were used to determine the independent predictive value of MEP status.
resultsAmong 133 patients (mean age 63.6 ± 12.2 years; 57.9% male), those with preserved MEPs (57.1%) demonstrated significantly better motor and functional outcomes at 90 days. MEP+ patients had higher FMA scores (61.0 ± 9.5 vs. 33.5 ± 25.5), Barthel Index scores (80.3 ± 25.0 vs. 57.7 ± 30.0), and greater odds of achieving minimal disability (mRS ≤ 1: 52.6% vs. 17.5%; all
conclusionsEarly MEP assessment is a valuable prognostic tool for upper-limb stroke recovery, supporting its routine incorporation into clinical practice.
