Age-related directional bias of fingertip force.
Article in Experimental brain research, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 23 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
We studied the direction of the three-dimensional fingertip force vector in young and old adults during a simple pressing task with the index finger. Ten young and ten old subjects pressed against a force plate with their index finger and maintained target forces that ranged from 2.5 to 15 N. Subjects viewed a display of the force normal to the force plate; forces tangential to the force plate were not displayed. Young adults produced fingertip forces that were nearly perpendicular to the plate at all target forces while old adults produced fingertip forces that deviated in the proximal direction of the horizontal plane, and ulnar direction of the vertical plane. The fingertip force deviated from the onset of pressing in both groups, but in young subjects the force aligned to perpendicular within 200 ms. Additional study is required to determine if these biased force vector directions contribute to clumsiness and slowing that are characteristic of fine manipulation in old age.
