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 coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a serious global issue. To prevent viral transmission, it is important to disinfect contaminated environmental surfaces and aerosols. We previously demonstrated that nano-sized electrostatic atomized water particles (NEAWPs) inactivate SARS-CoV-2. Herein, we focused on the underlying mechanisms. Morphological observation by transmission electron microscopy revealed that compared with NEAWPs-untreated virus, the shapes of particles corresponding to the size of SARS-CoV-2 particles were distorted significantly when exposed to NEAWPs. The amounts of viral RNA and protein in NEAWPs-treated SARS-CoV-2 showed a significantly greater decline than those in viruses unexposed to NEAWPs. Furthermore, much less NEAWPs-treated SARS-CoV-2 than NEAWPs-untreated virus bound to host cells. These results strongly suggest that NEAWPs damage the viral envelope, as well as viral protein and RNA, thereby impairing the ability of the virus to bind to host cells. Reactive oxygen species in NEAWPs may be involved in the inactivating effects on SARS-CoV-2.
