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
Double-stranded RNAs (dsRNAs) associated with chloroplasts and mitochondria have been found in the coenocytic green alga Bryopsis cinicola. In this study we report molecular properties of the four chloroplast-associated dsRNAs (BDRC1 to BDRC4). The longest dsRNA molecule (BDRC1) was sequenced entirely (1959 bp) and a single large ORF of 1722 bp was found within it. Database searches revealed similarities between the deduced amino acid sequence of this ORF and RNA-dependent RNA polymerase (RdRp) sequences from several RNA viruses. The most similar sequence in the database was the RdRp of beet cryptic virus 3. Phylogenetic analysis revealed that the RdRp-like sequence of BDRC1 can be placed in the Partitiviridae clade. To detect autonomous replication of these dsRNAs, RdRp assays were carried out with actinomycin D, which is an inhibitor of DNA-dependent RNA synthesis. Incorporation of [alpha-32P]UTP was detected specifically in the chloroplast and mitochondrial dsRNAs, indicating that both the chloroplast dsRNAs (BDRCs) and the mitochondrial dsRNA (BDRM) of B. cinicola are RNA replicons. The green alga B. cinicola harbors different dsRNA replicons in its chloroplasts and mitochondria.
