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 messageThe newly discovered determinate plant growth habit of Brassica napus is a potential trait that might contribute to the genetic improvement of rapeseed. Brassica napus is an important species of rapeseed and has an indeterminate growth habit. However, a determinate inflorescence strain (4769) has been discovered among doubled haploid (DH) lines obtained from a spring B. napus × winter B. napus cross. We assessed the effect of the determinate growth habit on agronomic traits. The results showed that determinacy is beneficial for reducing plant height and flowering time, advancing maturity and maintaining productivity. We also investigated the inheritance of determinacy. A genetic analysis revealed that the phenotype of the determinate trait is controlled by one recessive gene, Bnsdt1. Mapping of the Bnsdt1 gene was subsequently conducted in BC1 and BC3 populations derived from combination 2014 × 4769. The results showed that the Bnsdt1 gene could be delimited to a region of approximately 220 kb, between 16,627 and 16,847 kb on A10. Within the target region, whole-genome re-sequencing identified two candidate regions (16,628-16,641 and 16,739-16,794 kb) of approximately 68 kb. A Blast analysis of the two candidate intervals found that BnaA10g26300D/GSBRNA2T00136426001 (BnTFL1) is homologous to the TFL1 gene of A. thaliana. Subsequently, quantitative reverse transcription (qRT)-PCR revealed that BnTFL1 was specifically expressed in the shoot apex. Collectively, the results of expression analysis provide preliminary evidence that BnTFL1 is a candidate gene for the inflorescence trait in 4769.
