Design and optimization of honeycomb structure in dual-link mechanism for revolving two-wing doors.
Article in Scientific reports, 2025. 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
This research puts forward a retractable dual-link mechanism to alleviate revolving two-wing doors collision risks. The mechanism is composed of three key parts: dual linkages, a base plate, and a connector. Through theoretical analysis and structural topology optimization with the goal of mass minimization, the existing constraints in traditional optimization methods that undermine structural integrity have been revealed. To resolve this issue, a trapezoid honeycomb structure has been designed as a substitute for the substrate. This design has achieved an 18.8% reduction in weight while preserving mechanical performance. Quasi-static compression tests and simulations have been employed to verify the energy absorption capacity and deformation characteristics of the honeycomb structure under significant impact loads. This comprehensive approach offers a novel solution for enhancing pedestrian safety.
