Effects of deep brain stimulation on vocal fold immobility in Parkinson's disease.
Article in Surgical neurology international, 2017. 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
backgroundVocal fold (VF) immobility is a rare, potentially fatal complication of advanced Parkinson's disease (PD). Previous reports suggest that subthalamic nucleus deep brain stimulation (STN-DBS) may influence laryngeal function, yet the role of STN-DBS on VF immobility remains unexplored. CASE DESCRIPTION: We report a case of a patient with advanced PD and bilateral VF immobility ultimately requiring a tracheostomy. To assess the effects of STN-DBS on vocal cord function and to correlate these effects with peripheral motor symptoms at different stimulation settings, the patient was evaluated before and after initiation of bilateral STN-DBS. Measures included direct observation of VF mobility via transnasal laryngoscopy, levodopa equivalent dose of anti-PD medication, and motor scores. High frequency (150 Hz) STN-DBS resulted in improved motor scores, reduced medication requirement, and modestly improved right VF abduction although insufficient for safe decannulation. Low frequency (60 Hz) stimulation resulted in lower motor scores, but without worsening VF abduction.
conclusionsSTN-DBS may play an important role in the neuromodulation of PD-induced laryngeal dysfunction, including VF mobility. Characterization of these axial symptoms is important when programming and evaluating responsiveness to DBS.
