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 high transmission and mortality rates associated with SARS-CoV-2 have led to tragic consequences worldwide. Large-scale whole-genome sequencing of the SARS-CoV-2 genome since its identification in late 2019 has identified many sequence changes and the emergence of novel strains, each described by co-segregation of a particular set of sequence variations. Variants designated G, alpha (B.1.1.7), beta (B.1.351), gamma (P.1), and delta (B.1.617.2) are important lineages that emerged sequentially and are considered variants of concern. A notable feature of the last four, each of which ultimately evolved from clade G, is the large number (≥ 20) of co-segregating sequence variations associated with them. Several variations are in the spike gene, and some variations are shared among or between strains. Meanwhile, observation of recurrent infections with the same or different SARS-CoV-2 lineages has raised concerns about the duration of the immune responses induced by the initial infection or the vaccine that was administered. While the alpha strain is sensitive to immune responses induced by earlier strains, the beta, gamma, and delta strains can escape antibody neutralization. Apart from random replication errors, intra-host RNA editing, chronic infections, and recombination are processes that may promote the accumulation of sequence changes in the SARS-CoV-2 genome. The known contribution of recombination to coronavirus evolution and recent data pertaining to SARS-CoV-2 suggest that recombination may be particularly important. Continued surveillance of the SARS-CoV-2 genome is imperative.
