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
Enveloped viruses have caused the majority of epidemics and pandemics over the past decade. Direct sensing of virus particles (virions) holds great potential for the functional analysis of enveloped viruses. Here, we explore a series of viral membrane-targeting amphipathic helical (AH) peptide-based molecular probes for the assessment of infectious titers of the human coronavirus 229E virus (HCoV-229E). The M2-protein-derived AH peptide is identified as a strong binder for HCoV-229E, and its conjugate with Nile Red, M2-NR, exhibits fluorogenic response upon selective binding to the viral membrane of HCoV-229E. We demonstrate that the response of M2-NR toward the HCoV-229E virus enables the rapid, simple, and reliable assessment of the infectivity of HCoV-229E. In addition, the present fluorescence assay for infectivity analysis is applicable to various kinds of enveloped virus including influenza A virus, herpes simplex virus-1, and lentivirus.
