Article in Movement disorders clinical practice, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07168850 (Focused Ultrasound Pallidotomy for Medication-Refractory Limb Dystonia), which is not on this map. Cited by 9 papers, 1 of them a synthesis that pooled it.

1 · What the graph read from it

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.

Abstract

Background: For safety reasons, both magnetic resonance-guided high-intensity focused ultrasound (MRgHiFUS) thalamotomy and pallidotomy are currently approved exclusively for unilateral treatment, but axial symptoms like levodopa-induced orofacial dyskinesia require a bilateral approach. Objectives: We report the first case of successful bilateral MRgHiFUS pallidotomy for peak-dose dyskinesia in a patient with Parkinson's disease (PD). Methods: The treatment decision was based on the patient's reluctance toward brain implants and pump therapies and the fact that he had limited access to a deep brain stimulation center in his home country. The treatment was planned as staged procedure with an interval of 18 months because of travel restrictions because of the coronavirus disease (COVID)-19 pandemic. Results: After the second treatment, levodopa-induced orofacial dyskinesia remitted and improved bradykinesia and rigidity with stable gait and good postural reflexes. Conclusions: This promising result suggests that in selected PD patients with dyskinesia, staged bilateral MRgHiFUS pallidotomy might be considered.
