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
backgroundThis study evaluates the efficacy of dry-fogged hydrogen peroxide (dHP) as an "untact" room disinfection automation system (URDAS) for rapid terminal room decontamination.
methodsThis prospective study was conducted at a university-affiliated hospital in Korea. After patient discharge, dHP technology was used to decontaminate single rooms. Environmental cultures were collected from inanimate surfaces and room air before and after the decontamination process. Routine manual cleaning and disinfection were performed only after environmental sampling during terminal decontamination.
resultsAfter applying URDAS using dHP, culture positivity in the surface samples decreased from 20.5% (16/78) to 5.1% (4/78). Particularly, bed-removable tables and bedsheets used by patients often remain contaminated even after disinfection. Thirty-six species were isolated from the air cultures before disinfection, which decreased to 23 species after disinfection, representing a 36.1% reduction. The most frequently isolated pathogens after disinfection were S. aureus on fabric materials from surface samples and Aspergillus species from air samples.
conclusionOur findings demonstrate that URDAS using dHP is an effective tool for disinfecting contaminated environmental surfaces and spaces in single isolation rooms with minimal risk of exposure to medical staff. However, further optimization is required to address the material- and pathogen-specific disinfection challenges.
