A case report: combined posterior subthalamic area and globus pallidus internus deep brain stimulation in Parkinson's disease.

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: Deep brain stimulation is a primary surgical treatment for advanced Parkinson's disease (PD). The globus pallidus interna (GPi) is a key target for this procedure. The posterior subthalamic area (PSA) serves as an effective target for tremor-dominant Parkinson's disease. However, it is less commonly utilized in conventional DBS surgery compared to the subthalamic nucleus (STN) or the ventral intermediate nucleus (VIM). There is currently no clinical research on the combined DBS surgery targeting both the PSA and the GPi, which is why we have conducted this study. Case report: We introduced a case of a patient with advanced PD. Due to the patient's primary manifestations of right-sided tremor and left-sided rigidity, along with significant dyskinesia on the left side, DBS implantation was performed in the left hemisphere targeting the PSA and in the right hemisphere targeting the GPi. The patient's UPDRS-III score decreased from 73 to 46 postoperatively, showing an improvement of approximately 36.99%, while the H-Y stage improved from stage 4 to 2.5, representing a 37.5% improvement. During the 6-months postoperative follow-up, the patient's PD symptoms were effectively controlled, with no significant adverse effects. Discussion: When advanced PD patients present with asymmetric and variable motor symptoms, combined DBS stimulation targeting both the GPi and the PSA is a viable treatment option.
