Molecular characterization of SARS-CoV-2 from the saliva of patients in the Republic of Korea in 2020.
Article in Health science reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Background and aims: Despite global vaccination efforts, the number of confirmed cases of coronavirus disease 2019 (COVID-19) remains high. To overcome the crisis precipitated by the ongoing pandemic, characteristic studies such as virus diagnosis, isolation, and genome analysis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are necessary. Herein, we report the isolation and molecular characterization of SARS-CoV-2 from the saliva of patients who had tested positive for COVID-19 at Proving Ground in Taean County, Republic of Korea, in 2020. Methods: We analyzed the whole-genome sequence of SARS-CoV-2 isolated from the saliva samples of patients through next-generation sequencing. We also successfully isolated SARS-CoV-2 from the saliva samples of two patients by using cell culture, which was used to study the cytopathic effects and viral replication in Vero E6 cells. Results: Whole-genome sequences of the isolates, SARS-CoV-2 ADD-2 and ADD-4, obtained from saliva were identical, and phylogenetic analysis using Bayesian inference methods showed SARS-CoV-2 GH clade (B.1.497) genome-specific clustering. Typical coronavirus-like particles, with diameters of 70-120 nm, were observed in the SARS-CoV-2 infected Vero E6 cells using transmission electron microscopy. Conclusion: In conclusion, this report provides insights into the molecular diagnosis, isolation, genetic characteristics, and diversity of SARS-CoV-2 isolated from the saliva of patients. Further studies are needed to explore and monitor the evolution and characteristics of SARS-CoV-2 variants.
