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 study genetic relatedness of two male sterility-inducing cytotypes, the phylogenetic relationship among three cytotypes of onions (Allium cepa L.) was assessed by analyzing polymorphisms of the mitochondrial DNA organization and chloroplast sequences. The atp6 gene and a small open reading frame, orf22, did not differ between the normal and CMS-T cytotypes, but two SNPs and one 4-bp insertion were identified in CMS-S cytotype. Partial sequences of the chloroplast ycf2 gene were integrated in the upstream sequence of the cob gene via short repeat sequence-mediated recombination. However, this chloroplast DNA-integrated organization was detected only in CMS-S. Interestingly, disruption of a group II intron of cox2 was identified for the first time in this study. Like other trans-splicing group II introns in mitochondrial genomes, fragmentation of the intron occurred in domain IV. Two variants of each exon1 and exon2 flanking sequences were identified. The predominant types of four variants were identical in both the normal and the CMS-T cytotypes. These predominant types existed as sublimons in CMS-S cytotypes. Altogether, no differences were identified between normal and CMS-T, but significant differences in gene organization and nucleotide sequences were identified in CMS-S, suggesting recent origin of CMS-T male-sterility from the normal cytotype.
