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
Male sterility is an important contributor to heterosis in Brassica napus L. The B. napus line 7-7365ABC is a recessive epistatic genic male sterile (REGMS) three-line system. The 7-7365A line with the genotype Bnms3ms3ms4ms4RfRf is male-sterile, while the 7-7365B line with the genotype BnMs3ms3ms4ms4RfRf is male-fertile, and 7-7365C with homozygous recessive genotypes at the three loci shows male fertility because the loss function of Bnrf gene causes the inhibition of the genetic trait of the double mutant Bnms3 Bnms4. Histological studies addressing male sterility, transcriptional regulation pathways and the role of abscisic acid (ABA) in the anther development of REGMS plants are reported here. In the male-sterile line 7-7365A, tapetum cell and microspore mother cell separation were affected, and this led to failure of microspore release. The activity of polygalacturonase and the expression of the pectin methylesterase gene (AT3g06830) were significantly downregulated. Nine genes were downregulated in 7-7365A compared to 7-7365B and 7-7365C, including genes specifically expressed in tapetum (A3, A9, MS1) and the ABA-responsive gene KIN1. ABA concentration in 7-7365B was significantly higher than in 7-7365A and 7-7365C in young flower buds. Furthermore, temperature treatment made some sterile 7-7365A flowers become fertile. The stamens in these flowers produced viable pollen, and filament elongation was restored to its level in 7-7365C. We propose that ABA might control the expression of genes involved in cell separation during early anther development. The REGMS phenotype could be controlled by a primary pathway of male sterile metabolism positively regulated by the BnMs3 gene and a supplementary pathway negatively regulated by the BnRf gene.
