Molecular characterization of a single mitochondria-associated double-stranded RNA in the green alga Bryopsis.
Article in Plant molecular biology, 1998. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
Mitochondria from the green alga Bryopsis sp. very often contained a 4.5 kb double-stranded RNA (dsRNA) at a defined level. Complementary DNA probes derived from the mitochondrial dsRNA hybridized with none of the algal chloroplast dsRNAs of 1.7 to 2.2 kb, but did hybridize with a similar-sized dsRNA among several dsRNAs from the mitochondria of B. maxima. Sequence analysis of the mitochondrial dsRNA from Bryopsis sp. revealed only two large, overlapping, open reading frames (ORFs) on one strand if UGA was taken as a non-termination codon, suggesting the independent phylogenetic evolution of the mitochondrial dsRNA. Consensus sequence for RNA-dependent RNA polymerase was found within the longer ORF (2472 bp) of the dsRNA. The overlapping 52 bp of the ORFs in different reading frames is suggestive of the occurrence of a -1 ribosomal frameshift in the mitochondrial translation system. The observed simple genetic structures suggest that the algal mitochondrial dsRNA might be deficient in a gene for movement from cell to cell in host plants and, hence, has a plasmid-like nature that is distinct from that of infectious plant viruses. The nature and origin of the endogenous dsRNAs of various sizes and their relationships are discussed.
