The effects of simulated +Gz and microgravity on intervertebral disc degeneration in rabbits.
Article in Scientific reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
The overall objective of this study was to test the hypothesis that +Gz (hypergravity/positive acceleration) and microgravity can both aggravate intervertebral disc degeneration (IVDD). Due to +Gz and microgravity, many pilots develop IVDD. However, the lack of animal models of IVDD under conditions of simulated +Gz and microgravity has hampered research on the onset and prevention of IVDD. Rabbits were randomly allotted to a control group, microgravity group, +Gz group, or mixed (+Gz + microgravity) group. A tail-suspension model was utilized to simulate a microgravity environment and an animal centrifuge to mimic +Gz conditions. After exposure to the above conditions for 4, 8, and 24 weeks, the body weights (BW) of animals in the control group gradually increased over time, while those of animals in the microgravity and mixed groups both decreased (p < 0.001). As compared with the control group, the proteoglycan content of animals in the other three groups was significantly reduced (F = 192.83, p < 0.001). The imageological, histopathological, and immunohistochemical changes to the L6-S1 intervertebral disc samples suggests that the effects of +Gz and microgravity can aggravate IVDD over time. The mixed effects of +Gz and microgravity had the greatest effect on degeneration and +Gz had a particularly greater effect than microgravity.
