Parkinson's disease tremor explained by reflex loop changes.
Article in Scientific reports, 2025. 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
Many Parkinson's Disease tremor behaviors that were considered hard to interpret can be explained by control systems modeling of mid-level motor control. The model in this paper includes stretch reflex loop with feedback delay and tonically controlled antagonist muscles. It also includes Basal Ganglia circuit that commands (schedules) gain changes in the reflex feedback loop. Computational analysis of the control systems model shows how the gain changes might turn the tremor on and off between pose maintenance and voluntary motion in the disease and normal state. The results might be useful for interpreting and tuning the effects of Parkinson's Disease treatments. They also provide new control systems engineering insight into mid-level motor control.
