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.

2 · The registry

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

backgroundNeurophysiological biomarkers in Parkinson's disease (PD) are increasingly used for deep brain stimulation (DBS). Their long-term utility is not clear, especially when transitioning to sensing-guided DBS years post-surgery.

objectivesBeta-band power, bursting activity, and periodic and aperiodic components of local field potentials recorded from DBS electrodes in the subthalamic nucleus (STN) were compared between a group of newly and chronically (6.7 ± 4.0 years) implanted PD patients. Clinical severity was rated using the Movement Disorder Society-Unified Parkinson's Disease Rating Scale-Part III (MDS-UPDRS-III).

resultsBeta-band power and burst amplitude were significantly higher and aperiodic offset and exponent were significantly lower in the chronically implanted cohort. Periodic peak frequency and power were not significantly different. Clinical severity correlated with cumulative burst time and burst rate. A longitudinal subset showed no change in peak frequency or power.

conclusionsSTN beta-band-related biomarkers inform disease state of de novo and chronic PD-DBS cohorts, with signal properties relevant for sensing-guided DBS preserved over time. © 2026 The Author(s).
