Article in Scientific reports, 2026. 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
Aiming at improving the structural performance of the high-precision turning-milling combined machine tool bed, a multi-objective collaborative optimization framework that integrates bionic design principles and the Taguchi method is developed in this study. This framework first extracts the static and dynamic characteristics of the bed structure through finite element simulation. Then, inspired by the honeycomb configuration as a bionic prototype, it innovatively redesigns the internal rib layout. Subsequently, systematic optimization of key dimensional parameters is conducted via Taguchi orthogonal experiments, ultimately establishing a mathematical model with the comprehensive objectives of mass reduction, deformation suppression, and natural frequency enhancement. The results show that the quality of the optimized bed is reduced by 6.7%, the maximum deformation is decreased by 6.15%, and the fourth-order natural frequency is increased by 2.8%. It achieves lightweighting while significantly enhancing the static and dynamic performance of the structure, providing a feasible path for the green design and performance improvement of high-precision machine tools.
