The rapeseed mitochondrial gene encoding a homologue of the bacterial protein Ccl1 is divided into two independently transcribed reading frames.

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
In the rapeseed mitochondrial genome we identified sequences that have a high similarity to those of a bacterial gene involved in the biogenesis of cytochromes c designated ccl1. The structure of this gene is quite unusual. In rapeseed mitochondria, the ccl1-homologous (orf577) sequence is divided into two parts, which are at least 45 kb apart. These two parts are transcribed separately and their transcripts are edited similarly to the homologous transcripts of wheat and Oenothera. However it was impossible to identify a mature transcript covering the whole coding region, a result that excludes a trans-splicing event. No other copy of this gene was found in either the nuclear genome or the mitochondrial genome. The protein product of orf577 is present in rapeseed mitochondria. These results raise the possibility that this divided gene might be functional and active in rapeseed mitochondria through a novel mechanism of gene expression.
