1 · What the graph read from it

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.

2 · The registry

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

In the context of emergency rescue helicopter flight training, where suspended motion mechanisms are crucial, this study presents the design of a suspended three-degree-of-freedom motion mechanism aimed at replicating yaw, roll, and pitch motions within the simulation cabin. The kinematic relationship between the moving platform in drive space, joint space and platform attitude is analyzed, and the Lagrangian method is used to establish the dynamic equations and solve the driving moment of the mechanism; The active branch is set to position mode to provide accurate position output, and the passive branch is set to force control mode to improve the force distribution problem of the branch and improve the overall motion coordination of the mechanism. Position control and force control complement each other to achieve force-position hybrid control, improve the stability of the motion system, optimize the dynamic performance, and provide a new idea for the design of this type of spatial redundant drive mechanism.
