1 · What the graph read from it

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.

2 · The registry

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 COVID-19 corona virus has become a world pandemic which started in December 2019 in Wuhan, China with no confirmed biological source. Various countries reported the genomic sequence of different isolates obtained from infected patients. This allowed us to obtain a number of 38 isolates of full genomic sequences. Alignment of nucleotide (nt) sequence was carried out using Clustal Omega multiple alignment service at the EBI website. Alignment of nt sequence and phylogenetic relationship revealed that the COVID-19 is a new viral strain and its biological source has not been yet detected. The expected orf pattern was different among isolates obtained from the same country or different countries as well as from SARS-CoV isolates or bats CoV suggesting different virus human interaction possibilities during infection and severity. All isolates had the main five orfs (1ab, S, M, N, E), whereas they differed in the expected accessory orfs. Being with the biological source of COVID-19 undetected, the role of human endogenous retrovirus (HERVs) in the regulation of the host cell gene expression or the encoding for products that could modulate COVID-19 infection and the spectrum of its symptoms is discussed.
