1 · What the graph read from it

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.

2 · The registry

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

The phenomenon of RNA editing has been found to occur in chloroplasts of several angiosperm plants. Comparative analysis of the entire nucleotide sequence of a gymnosperm [Pinus thunbergii (black pine)] chloroplast genome allowed us to predict several potential editing sites in its transcripts. Forty-nine such sites from 14 genes/ORFs were analyzed by sequencing both cDNAs from the transcripts and the corresponding chloroplast DNA regions, and 26 RNA editing sites were identified in the transcripts from 12 genes/ORFs, indicating that chloroplast RNA editing is not restricted to angiosperms but occurs in the gymnosperm, too. All the RNA editing events are C-to-U conversions; however, many new codon substitutions and creation of stop codons that have not so far been reported in angiosperm chloroplasts were observed. The most striking is that two editing events result in the creation of an initiation and a stop codon within a single transcript, leading to the formation of a new reading frame of 33 codons. The predicted product is highly homologous to that deduced from the ycf7 gene (ORF31), which is conserved in the chloroplast genomes of many other plant species.
