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
We previously reported that Sestd1 KO phenocopies Dact1 KO in mice, consistent with a model in which Sestd1 and Dact1 act together to form a crucial functional complex that regulates Vangl2 in the Wnt/Planar Cell Polarity (PCP) pathway. Here, we show that Dvl2, a binding partner of Dact1, also forms complexes with Sestd1, and does so independently of both Dact1 and Vangl2. In cell-based assays, whereas Sestd1 does not alter Dvl2 activation of the Wnt/β-catenin signaling pathway, Dvl2 enhances activation of Rho family GTPases by Dact1 and Sestd1, consistent with a role in the PCP pathway. In mice, although Dvl2 KO is recessive in an otherwise wild type background, it leads to dominant embryonic lethality in either the Sestd1 or Dact1 KO background. This genetic synergy stands in contrast to the epistasis we have previously reported between Sestd1 and Dact1 KO, and suggests independent or semi-independent functions for Dvl2 vs. Sestd1/Dact1 in the regulation of the PCP pathway during development. In conclusion, biochemical and genetic interactions between Dvl2, Sestd1, and Dact1, in addition to prior reported interactions between these same molecules and Vangl2, suggest that all these gene products can form complexes together and regulate the PCP pathway during mammalian development. However, Sestd1 and Dact1 have a closely allied function in the post-translational regulation of Vangl2 that is at least partially distinct from the functions of Dvl2 in this pathway.
