Comparison of oscillatory activity in substantia nigra pars reticulata between Parkinson's disease and dystonia.
Article in NPJ Parkinson's disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Parkinson's disease (PD) is associated with disrupted neural activity in the substantia nigra, but its electrophysiological changes remain underexplored. This study investigates the oscillatory patterns of substantia nigra pars reticulata (SNr) in PD, compared to dystonia (DT). Intraoperative recordings of the SNr were obtained from 20 PD and 16 DT patients during DBS surgery. Spectral power, neuronal firing rate, beta burst dynamics, and correlation analysis of the SNr signal were analyzed. PD patients exhibited increased alpha and beta power, elevated firing rates, and reduced aperiodic exponent values in SNr compared to DT. PD beta bursts showed prolonged durations and fewer short bursts. Beta power negatively correlated with motor symptom improvement rates in PD but not in DT patients. These findings highlight pathological beta power in SNr of PD, which indicates that SNr-DBS may offer a future therapeutic avenue for PD.
