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
key messageBrKCS6 encoding 3-ketoacyl-CoA synthases was cloned through MutMap and KASP analysis, and its function was verified via allelic mutants in Chinese cabbage. Bright and glossy green appearance is an attractive commodity character for leafy vegetables and is mainly caused by the absence of epicuticular wax crystals. In this study, two allelic epicuticular wax crystal deficiency mutants, wdm9 and wdm10, were obtained from an EMS mutagenesis population of Chinese cabbage (Brassica rapa L. ssp. pekinensis). Genetic analysis revealed that the mutant phenotype was controlled by a recessive nuclear gene. BrKCS6 encoding 3-ketoacyl-CoA synthases was identified as the candidate gene by MutMap and KASP analysis. A SNP (G to A) on BrKCS6 in wdm9 led to the amino acid substitution from serine (S) to phenylalanine (F), and another SNP (G to A) in wdm10 resulted in the amino acid substitution from serine (S) to leucine (L). Both SNPs are located in the ACP_syn_III_C conserved domain, corresponding to two highly conserved sites among BrKCS6 and its homologs. These two amino acid substitutions changed the secondary structure and the three-dimensional structure of BrKCS6 protein. qRT-PCR results showed that the relative expression of BrKCS6 significantly decreased in the flower, stem, and leaves in mutant, and the relative expressions of the downstream key genes of BrKCS6 were down-regulated in mutant. We were the first to clone the precious glossy bright gene BrKCS6 which has a great potential for commodity quality breeding in Chinese cabbage.
