EGL-38/Pax coordinates development in the Caenhorhabditis elegans egg-laying system through EGF pathway dependent and independent functions.
Article in Mechanisms of development, 2019. 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
Paired box (Pax) proteins function as regulators of coordinated development in organogenesis by controlling factors such as cell growth and differentiation necessary to organize multiple cell types into a single, cohesive organ. Previous work has suggested that Pax transcription factors may regulate diverse cell types through participation in inductive cell-to-cell signaling, which has not been well explored. Here we show that EGL-38, a Pax2/5/8 ortholog, coordinates differentiation of the C. elegans egg-laying system through separate autonomous and non-autonomous functions synchronized by the EGF pathway. We find that EGL-38 protein is expressed at the correct times to both participate in and respond to the EGF pathway specifying uterine ventral (uv1) cell fate, and that EGL-38 is required for uv1 expression of nlp-2 and nlp-7, which are both markers of and participants in uv1 identity. Additionally, we have separated uv1 cell placement and gene expression as distinct hallmarks of uv1 identity and specification, with different dependencies on EGL-38. The parallels between EGL-38 participation in cell signaling events and previous Pax studies argue that coordination of signaling and response to an inductive pathway may be a common feature of Pax protein function.
