Design and dynamics of space- station-based one-degree-of-freedom repeatedly deployable exposure platform.

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
For cosmic-dust experiments on the space station, this paper proposes a one-degree-of-freedom repeatedly deployable exposure platform supporting multiple panels. A 4-panel module forms the basic unit and, through a modular library, scales to any panel count with a folding ratio of 14.09 : (1) a uniform acceleration-deceleration driving strategy at the control end or motor is proposed. Kinematic models define the motion space for arbitrary panel numbers. Lagrange dynamics models predict torque demand versus panel number and deployment period. For the 4-panel case, the two strategies need 0.0777 N m and 0.0972 N m at 40 s; with a 1 N m target the minimum periods shorten to 14.05 s and 12.63 s. A 4-panel prototype verified smooth, synchronized deploy-retract. Positioning tests showed absolute accuracies better than 5.42 ± 0.60 mm and repeatability finer than 46 ± 2 μm on all axes, providing a validated basis for future space exposure platforms.
