[Optimization of Radiation-shielding Wall Thickness and Evaluation of Attenuation Performance Due to Deterioration].
Article in Jugan geon-gang gwa jilbyeong, 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
In accordance with Article 37 of the Medical Service Act in the Republic of Korea, medical institutions must be equipped with radiation-shielding facilities to utilize radiation for diagnostic purposes. Radiation-shielding facilities use materials such as lead, concrete, and lead glass and are designed to shield against radiation and prevent harmful effects on the human body. Therefore, determining the appropriate thickness of radiation protection walls based on radiation intensity is crucial in these facilities. In this study, we employed Monte Carlo simulations to model a radiation protection wall constructed in a clinical setting and composed of three layers: concrete-lead-concrete. The optimal shielding thickness was calculated for this configuration. Furthermore, given that radiation shielding facilities can deteriorate over time owing to external factors, potentially reducing their shielding effectiveness, we evaluated the shielding efficiency under three hypothetical aging scenarios. This study aims to assess the optimal shielding thickness and the impact of aging on the shielding efficiency of radiation-shielding walls.
