The L-A dsRNA Virus and Its Satellites: Totiviruses and Killers in
Review in Viruses, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
A secreted protein toxin encoded by a satellite dsRNA-enabled dissection of the genetic control of replication and expression of a single-segment dsRNA virus, the first Totivirus, L-A. Among the then-novel findings were i. "head-full replication", ii. a supposedly forbidden "T = 2" capsid symmetry based on an asymmetric dimer, iii. a host N-acetyltransferase whose modification of the coat protein is necessary for packaging, iv. Kex1 and Kex2 pro-toxin peptidases leading to discovery of the pre-pro-insulin processing enzymes, and v. specific viral (+) strand sites/structures needed for RNA packaging and (-) strand synthesis. L-A viral (+) strands made in the particle are extruded to the cytoplasm. Those destined for translation are 5' 7meGMP-capped by a coat protein activity that steals the cap from cellular mRNAs. (+) strands destined for encapsidation in new coats are not capped. Three host-encoded anti-viral systems were found, one based on blocking translation of the viral non-polyA mRNAs (Ski2,3,8 complex), another a 5'->3' exoribonuclease specific for uncapped molecules (such as the viral (+) strands)(Ski1/Xrn1), and the third a mitochondrial nuclease released in cells undergoing meiosis/sporulation (Nuc1). All of these systems protect cells from virus-induced pathology and have clear animal homologs. The 3' polyA of yeast mRNAs is dispensable for translation in
