Study on the loss of load-carrying capacity of thin-walled composite columns with closed cross-sections.
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
The subject of the study was thin-walled composite columns with a closed cross-section. The aim of the research was to analyse the failure of compressed thin-walled sections with three cross-section shapes and four composite lay-ups. The study investigated the effects of column cross-section shape and composite lay-up on loss of load-carrying capacity. Experimental studies of the axial compression of thin-walled composite structures were conducted using interdisciplinary research methods, thereby determining, among other things, post-buckling equilibrium paths and modes of structural failure. In numerical simulations, the research was conducted using original finite element method models, including a failure model based on progressive failure analysis. The novelty of the present paper was the evaluation of the load capacity of profiles with closed sections, with particular attention to the influence of cross-section shape and composite-ply arrangement. The experimental and numerical results of the study were in quantitative and qualitative agreement.
