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
We report here the presence of dsRNA mycoviruses in a Korean isolate of Rosellinia necatrix. A multiple band pattern of double-stranded RNA (dsRNA) from R. necatrix suggested mixed mycovirus infection. Next-generation sequencing analysis of purified dsRNAs indicated the presence of two dsRNA mycoviruses related to the members of families "Fusagraviridae" (proposed) and Partitiviridae. The first dsRNA virus revealed that the complete genome sequence was 8868 bp in size and contained two large open reading frames (ORFs 1 and 2), overlapped by 22 bp containing a canonical (- 1) slippery heptanucelotide sequence of UUUAAAC. The deduced amino acid sequence of ORF1 and ORF2 showed highest similarity to the hypothetical protein and RNA-dependent RNA polymerase (RdRp) of Rosellinia necatrix fusagravirus 3 (RnFGV3). Phylogenetic analysis showed that this dsRNA virus clustered with RnFGV3 and other fusagraviruses. Gene organization, sequence similarity, and phylogenetic analysis indicate that this virus seems to belong to a novel species of "Fusagraviridae", which we have named Rosellinia necatrix fusagravirus 4. The second virus has two dsRNA segments with sizes of 1907 bp and 1918 bp, each of which encoded a single ORF showing highest similarity to the RdRp and capsid protein of known members of Partitiviridae. Evaluation of genome structure, sequence similarity, and phylogeny indicate this to be a new member of the genus Alphapartitivirus in the family Partitiviridae, hereafter designated as Rosellinia necatrix partitivirus 26. This is the first report of the presence of a fusagravirus in an Asian R. necatrix isolate and of its mixed infection with a partitivirus.
