Kinetics and Kinematics of Shape Tracing in Children with Probable Developmental Coordination Disorder (pDCD).
Article in Children (Basel, Switzerland), 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
backgroundChildren with developmental coordination disorder (DCD) exhibit visual-motor deficits affecting handwriting. Shape tracing, a key prerequisite for handwriting, supports motor and cognitive development but remains underexplored in research, particularly in objectively studying its role in children with DCD.
objectivesTo compare the kinetics (pressure applied to the writing surface) and kinematics (spatial and temporal aspects) of shape tracing in children with pDCD to those of typically developing (TD) peers utilizing a digitized tablet.
methodsA total of 27 children with pDCD aged 7 to 12 years and 27 TD children matched by age and gender traced five unique shapes resembling print letters onto a digitized tablet. Participants' performance measurements included precision, time, smoothness, velocity, and pressure.
resultsThe findings revealed lower precision, longer duration, more smoothness but less consistency, lower velocity, and less pressure application in the pDCD group.
conclusionsThis research underlies the mechanisms of shape-tracing difficulties in children with DCD. Insights into early shape-tracing processes beyond product outcomes are essential for therapeutic and educational interventions, with digitized tablets offering a novel tool for assessing graphomotor skills in children with DCD.
