Effects of repetitive peripheral magnetic stimulation on upper extremity motor function recovery after stroke: a meta-analysis and dose-response study.
Synthesis in Frontiers in neurology. 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
Background: Repetitive peripheral magnetic stimulation (rPMS), a representative non-invasive neuromodulation technique, is widely utilized for the recovery of motor dysfunction following stroke. Although its clinical efficacy has been confirmed, discrepancies among studies and the optimal rPMS stimulation parameters remain unclear. This study aims to systematically analyze and quantitatively evaluate the optimal stimulation parameters using rPMS parameter subgroups extracted from existing studies. Methods: Conducted in accordance with PRISMA guidelines, this study searched for research related to rPMS and the Fugl-Meyer Assessment for Upper Extremity (FMA-UE) in stroke patients. A systematic review and meta-analysis of the aggregated studies were then performed. Furthermore, a robust error meta-regression (REMR) model was employed to explore the non-linear dose-response relationship between rPMS stimulation parameters (frequency, intensity, duration, and treatment days) and FMA-UE scores. Results: A total of 14 trials ( Conclusion: Under optimal parameter windows, the therapeutic mechanism of rPMS may be associated with triggering homeostatic plasticity and beta-band corticomuscular coherence. The greatest benefits are obtained particularly with neural-targeted protocols during the subacute phase of stroke, utilizing low frequency (≤20 Hz), moderate-to-low intensity (20-55% MSO), and an extended treatment course (≥21 days). In conclusion, current evidence provides a novel scientific basis and clinical reference for the application of rPMS in stroke rehabilitation.
