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
The genus Antirrhinum has been used as a model to study self-incompatibility extensively. The multi-allelic S-locus, carrying a pistil S-RNase and dozens of S-locus F-box (SLF) genes, underlies the genetic control of self-incompatibility (SI) in Antirrhinum hispanicum. However, there have been limited studies on the genomic organization of the S-locus supergene due to a lack of high-quality genomic data. Here, we present the chromosome-level reference and haplotype-resolved genome assemblies of a self-incompatible A. hispanicum line, AhS7S8. For the first time, 2 complete A. hispanicum S-haplotypes spanning ∼1.2 Mb and containing a total of 32 SLFs were reconstructed, whereas most of the SLFs derived from retroelement-mediated proximal or tandem duplication ∼122 Mya. Back then, the S-RNase gene and incipient SLFs came into linkage to form the pro-type of type-1 S-locus in the common ancestor of eudicots. Furthermore, we detected a pleiotropic cis-transcription factor (TF) associated with regulating the expression of SLFs, and two miRNAs may control the expression of this TF. Interspecific S-locus and intraspecific S-haplotype comparisons revealed the dynamic nature and polymorphism of the S-locus supergene mediated by continuous gene duplication, segmental translocation or loss, and TE-mediated transposition events. Our data provide an excellent resource for future research on the evolutionary studies of the S-RNase-based self-incompatibility system.
