Disturbances in human position sense during alterations in gravity: a parabolic flight experiment.
Article in Experimental brain research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Under conditions of weightlessness human position sense appears to deteriorate. This was tested, employing three methods of measurement: two-arm matching, one-arm pointing and one-arm repositioning, carried out during parabolic flight. In hypergravity (1.8G), position sense errors in a matching task increased significantly from the value during horizontal flight (1G) of + 2.5° (± 3.8° SD), to + 3.5° (± 3.3°). For pointing, errors increased significantly from + 9.1° (± 4.4°) to + 11.2° (± 4.4°). In microgravity (0G), matching errors fell significantly to + 0.35° (± 3.5°), while in pointing the fall was not significant. For repositioning, there were no significant changes in errors in either hypergravity or microgravity. It is proposed that the errors in matching and pointing are a consequence of the force of gravity acting at the elbow joint to alter the position signal coming from muscle and joint receptors. For repositioning, memory of the test angle was stored centrally, to be reproduced independently of any changes in gravity.
