Prognostic Value of Spontaneous Activity on Laryngeal Electromyography for Recovery of Vocal Fold Motion: A Systematic Review of Observational Studies.
Review in Current health sciences journal. 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-Vocal fold motion impairment resulting from laryngeal nerve injury poses a recurring prognostic dilemma in clinical practice. While laryngeal electromyography (LEMG) has been increasingly adopted as an objective tool for neuromuscular assessment, the specific prognostic value of spontaneous activity for predicting recovery of vocal fold motion remains incompletely defined. This systematic review aimed to evaluate the relationship between the presence of spontaneous activity on LEMG and subsequent vocal fold motion recovery across observational studies. Methods-A systematic search of MEDLINE (via PubMed), Embase, Scopus and the Cochrane Library databases was conducted in accordance with PRISMA guidelines, covering publications up to March 2026. Results-Across the included studies, the presence of spontaneous activity on LEMG-particularly fibrillation potentials-was consistently associated with poor recovery of vocal fold motion. Patients demonstrating active denervation potentials showed significantly lower rates of meaningful functional recovery compared to those in whom spontaneous activity was absent. This association held across multiple etiological subgroups, including post-surgical and idiopathic cases, though the strength of the relationship varied with the timing of LEMG relative to injury onset and the duration of follow-up. Conclusions-Spontaneous activity on LEMG represents a clinically meaningful predictor of unfavorable prognosis for vocal fold motion recovery. Standardization of LEMG protocols and reporting criteria across future studies remains essential to strengthen the evidence base in this field.
