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

Here, a novel double-stranded RNA (dsRNA) mycovirus, tentatively designated Fusarium oxysporum polymycovirus 1 (FoPmV1), was isolated from Fusarium oxysporum, a phytopathogenic fungus that causes tobacco root rot. The genome of FoPmV1 consists of eight dsRNA segments, referred to as dsRNA1 to dsRNA8, with lengths of 2440 bp, 2276 bp, 2042 bp, 1303 bp, 1144 bp, 1064 bp, 1004 bp, and 913 bp, respectively. Sequence analysis revealed that these dsRNA segments encode 8 open reading frames (ORFs): ORF1 (771 amino acids, aa), ORF2 (699 aa), ORF3 (622 aa), and ORF4 (304 aa) encode an RNA-dependent RNA polymerase (RdRp), scaffold protein, methyltransferase, and coat protein (PASRP), respectively. While ORF5 (304 aa), ORF6 (161 aa), ORF7 (167 aa), and ORF8 (211 aa) encode proteins with unknown functions. BLAST analysis revealed that the RdRp of FoPmV1 shares the maximal sequence identity of 75.75% with the RdRp of Fusarium redolens polymycovirus 1. Phylogenetic analysis based on the RdRp sequence clustered FoPmV1 robustly within the family Polymycoviridae. Overall, this research represents the first report of a polymycovirus infecting F. oxysporum.
