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
purposeThis study aimed to examine how vestibular dysfunction influences spatial perception and motor output, using drawing tasks as a tool to explore changes in body schema.
methodsTwenty patients with otolith dysfunction were compared to eight astronauts tested before, during, and after six months of exposure to microgravity aboard the International Space Station. Participants were instructed to draw squares, circles, and crosses, and write words both horizontally and vertically. Patients performed the tasks using pen and paper, whereas astronauts completed them on a digital tablet in microgravity.
resultsWhen performing these tasks with eyes closed, vestibular patients frequently produced drawings and handwriting that were more vertically compressed compared to when their eyes were open. Similarly, astronauts exhibited greater vertical compression in drawings and handwriting during spaceflight compared to their preflight performance.
conclusionThese findings highlight the critical role of vestibular input in integrating multisensory information to preserve consistent spatial representations.
