Long-Term Quality of Life Trend after Subthalamic Stimulation for Parkinson's Disease: An Updated Systematic Review and Meta-Analysis.

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 of the subthalamic nucleus (STN-DBS) is a well-established treatment for Parkinson's Disease (PD). However, the long-term trajectory of Quality of Life (QoL) following STN-DBS remains underexplored.
objectivesWe aimed to conduct a systematic review and meta-analysis to assess QoL trends up to five years after STN-DBS.
methodsWe systematically searched PubMed, Embase, and Cochrane databases from inception to August 2024 for studies involving PD patients treated with bilateral STN-DBS, evaluating QoL using the Parkinson's Disease Questionnaire (PDQ), with a minimum follow-up of 12 months post-surgery. Continuous outcomes were pooled using standardized mean differences (SMD), and statistical analyses were conducted using R version 4.3.2.
resultsOut of 4106 screened articles, 42 studies with a total of 2767 patients were included in the meta-analysis. QoL improvements were observed up to 36 months post-surgery (SMD 0.83; 95% CI 0.29 to 1.37), followed by a decline to pre-operative levels at 60 months (SMD -0.06; 95% CI -0.26 to 0.15). Subdomain analysis at 60 months revealed significant deterioration in cognitive function and communication. Meta-regression indicated that QoL improvements were independent of clinical and sociodemographic factors such as age, sex, and disease duration; however, there was a correlation with mean baseline PDQ (P = 0.01).
conclusionsThis meta-analysis provides long-term QoL trends following STN-DBS, highlighting a further need to explore the factors driving the decline in QoL and develop strategies to mitigate this deterioration.
