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
To identify regions of the mitochondrial genome potentially involved in the expression of alloplasmic 'Tournefortii-Stiewe' cytoplasmic male sterility (CMS) in Brassica napus, transcripts of 25 mitochondrial genes were analysed in fertile and near isogenic male-sterile plants (BC(8) generation). Differences were detected in the transcription of genes for subunit 9 of ATP synthase (atp9), cytochrome b (cob) and subunit 2 of NADH dehydrogenase (nad2). Structural analysis of these gene regions revealed differences in genome organisation around atp9 between male-sterile and fertile plants. Three atp9 genes, two of which were hitherto unknown, are present in the mitochondria of CMS plants, and rearrangements upstream of one of these genes have generated a chimeric 193-codon ORF, designated orf193. This region is transcribed as a CMS specific bi-cistronic mRNA of 1.58 kb comprising orf193 and atp9. The level of the aberrant 1.58-kb transcript is reduced in plants restored to fertility by as yet uncharacterized nuclear genes. orf193 encodes a polypeptide of 22.7 kDa which exhibits partial sequence identity to the subunit 6 of the ATP synthase complex. However, as it forms an uninterrupted ORF with one of the newly discovered atp9 genes it may also be translated as a chimeric 30.2-kDa protein. It is likely that either or both gene products interfere with the function or assembly of the mitochondrial F(0)F(1)-ATP synthase, thus impairing the highly ATP-dependent process of pollen development. The novel molecular features of alloplasmic 'Tournefortii-Stiewe' CMS are discussed with respect to the other known mechanisms of CMS in B. napus.
