Molecular characterization of a new endornavirus inhabiting the ectomycorrhizal fungus Hygrophorus penarioides.
Article in Brazilian journal of microbiology : [publication of the Brazilian Society for Microbiology], 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Viruses hosted by uncultivated fungi have been poorly studied. We carried out studies to characterize a large dsRNA segment (~20 kbp) detected in the basidiomycetous, ectomycorrhizal fungus Hygrophorus penarioides. The dsRNA was gel-purified and its randomly amplified cDNA fragments were used for high throughput sequencing (HTS). Reads were de novo assembled and BLASTx analysis revealed sequence similarity to viruses of the family Endornaviridae. The 5' and 3' terminal sequences of the dsRNA segment were determined by performing RNA ligase-mediated rapid amplification of cDNA ends (RLM-RACE). The full-length cDNA sequence of the putative endornavirus comprises 16,785 nt and contains a single, long open reading frame which encodes for a polyprotein of 5522 aa with conserved domains for cysteine-rich region, helicase, glycosyltransferase, and RNA-dependent RNA polymerase. The virus was named Hygrophorus penarioides endornavirus 1 (HpEnV1). A BLASTp search performed using the polyprotein sequence revealed that the most closely related, fully sequenced endornavirus to HpEnV1 is Ceratobasidium endornavirus B.
