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
Objective: To evaluate the disinfection efficacy of a third-generation gallium nitride (GaN)-based deep ultraviolet (UVC) LED disinfection cabinet on often-touch surfaces of small advanced electronic devices in hospital clinical environments, and to provide evidence for its application in hospital infection control. Methods: A total of 329 device surfaces from 10 randomly selected departments were sampled: 66 computer mice, 151 mobile phones, 53 Personal Digital Assistants (PDAs), 29 electronic glucometers, and 30 electronic sphygmomanometers. Pre-disinfection bacterial contamination levels were assessed. The UVC-LED cabinet was used for disinfection (10-min cycle, 24 mJ/cm Results: A total of 658 sampling points (329 pre- and post-disinfection) were monitored. Before disinfection, 57.1% of device surfaces showed microbial contamination, with mice and cleaning staff's mobile phones exhibiting relatively severe bacterial contamination. After disinfection, 97.9% of device surfaces showed bacterial colony counts reduced to 0 CFU, with an average natural bacteria eradication rate of 99.9% (range ≥90%). Conclusion: High-frequency use of small advanced electronic devices by healthcare workers poses hospital infection risks. Deep LED Ultraviolet-C disinfection effectively reduces microbial load on surfaces of devices incompatible with chemical disinfectants or heat. It is recommended as a routine disinfection measure for hospital infection control. This study demonstrates high efficacy under controlled conditions; however, real-world effectiveness may be influenced by factors such as device positioning and surface shadows.
