Effects of deep brain stimulation on functional autonomy and quality of life in Parkinson's disease: A systematic review and meta-analysis.
Review in Journal of Parkinson's disease, 2026. 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
BackgroundDeep brain stimulation (DBS) of the subthalamic nucleus (STN) is an established therapy for advanced Parkinson's disease (PD), primarily targeting motor complications refractory to pharmacological treatment. However, its long-term impact on functional autonomy and quality of life (QoL) remains debated.ObjectiveThis systematic review with meta-analysis aimed to evaluate the effects of STN-DBS on autonomy and QoL in people with PD.MethodsFollowing PRISMA guidelines, a systematic search of PubMed, Scopus, Embase and Web of Science was conducted to identify studies including adults with PD treated with STN-DBS and reporting measures of autonomy and/or quality of life.ResultsThirty-two studies met inclusion criteria. Meta-analyses showed effect estimates favoring DBS at 6 months (SMD = 0.83[0.38;1.29]) and at 1 year (SMD = 0.49[-0.02;0.99]) for autonomy. Similar trends were observed for QoL, with SMD = 0.60[0.49;0.71] at 6 months and SMD = 0.48[0.0;0.96] at 1 year.At 2 years, small but significant pooled effects persisted, for both autonomy SMD = 0.40[0.13;0.67] and QoL SMD = 0.25[-0.04;0.53]. However, at 5 years, pooled effects were no longer statistically significant for either autonomy SMD = 0.37[-0.55;1.29] or QoL SMD = -0.01[-0.25;0.22], indicating a progressive attenuation of benefit over time.ConclusionsSTN-DBS provides robust short- and mid-term benefits in functional autonomy and QoL in PD. Long-term outcomes are variable and influenced by disease progression and non-motor symptoms. Standardized outcome reporting, larger multicenter trials, and integration of rehabilitative and psychosocial interventions are needed to optimize benefits.
