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 messageA candidate gene Bndm1 related to determinate inflorescence was mapped to a 128-kb interval on C02 in Brassica napus. Brassica napus plants with determinate inflorescence exhibit improved traits in field production, such as lower plant height, improved lodging resistance, and consistent maturity. Compared to plants with indeterminate inflorescence, such features are favorable for mechanized harvesting techniques. Here, using a natural mutant 6138 with determinate inflorescence, it is demonstrated that determinate inflorescence reduces plant height significantly without affecting thousand-grain weight and yield per plant. Determinacy was regulated by a single recessive gene, Bndm1. Using a combination of SNP arrays and map-based cloning, we mapped the locus of determinacy to a 128-kb region on C02. Based on sequence comparisons and the reported functions of candidate genes in this region, we predicted BnaC02.knu (a homolog of KNU in Arabidopsis) as a possible candidate gene of Bndm1 for controlling determinate inflorescence. We found a 623-bp deletion in a region upstream of the KNU promoter in the mutant. This deletion led to the significant overexpression of BnaC02.knu in the mutant compared to that in the ZS11 line. The correlation between this deletion and determinate inflorescence was examined in natural populations. The results indicated that the deletion affected the normal transcription of BnaC02.knu in the plants with determinate inflorescence and played an important role in maintaining flower development. This study presents as a new material for optimizing plant architecture and breeding novel canola varieties suitable for mechanized production. Moreover, our findings provide a theoretical basis for analyzing the molecular mechanisms underlying the formation of determinate inflorescence in B. napus.
