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

backgroundFor People with Parkinson's (PwP), motor disturbances affecting the dominant upper extremity often impacts ability to perform tasks such as writing or typing and may confound cognitive test performances with graphomotor responding.

objectivesWe explored association between upper extremity impairment and graphomotor cognitive test performances in a clinical sample of moderately advanced PwP pursuing Deep Brain Stimulation (DBS).

methodsA retrospective chart review was conducted of 80 consecutive right hand dominant PwP who completed pre-DBS neuropsychological evaluations. Right upper extremity (RUE) impairment was measured using MDS-UPDRS Part 3. Non-parametric correlations examined associations between RUE impairment and tests involving graphomotor (trail making, letter cancellation, visual memory) versus oral responding (fluency, digit span, verbal memory).

resultsNo statistically significant associations were observed between RUE motor impairment and graphomotor test performances.

conclusionsMinimal impact of dominant RUE impairment on graphomotor tasks in moderately advanced PwP supports application in clinical and research settings.
