Paxillin genes and actomyosin contractility regulate myotome morphogenesis in zebrafish.
Article in Developmental biology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Paxillin (Pxn) is a key adapter protein and signaling regulator at sites of cell-extracellular matrix (ECM) adhesion. Here, we investigated the role of Pxn during vertebrate development using the zebrafish embryo as a model system. We have characterized two Pxn genes, pxna and pxnb, in zebrafish that are maternally supplied and expressed in multiple tissues. Gene editing and antisense gene knockdown approaches were used to uncover Pxn functions during zebrafish development. While mutation of either pxna or pxnb alone did not cause gross embryonic phenotypes, double mutants lacking maternally supplied pxna or pxnb displayed defects in cardiovascular, axial, and skeletal muscle development. Transient knockdown of Pxn proteins resulted in similar defects. Irregular myotome shape and ECM composition were observed, suggesting an "inside-out" signaling role for Paxillin genes in the development of myotendinous junctions. Inhibiting non-muscle Myosin-II during somitogenesis altered the subcellular localization of Pxn protein and phenocopied pxn gene loss-of-function. This indicates that Paxillin genes are effectors of actomyosin contractility-driven morphogenesis of trunk musculature in zebrafish. Together, these results reveal new functions for Pxn during muscle development and provide novel genetic models to elucidate Pxn functions.
