Expression patterns of duplicated snail genes in the leech Helobdella.
Article in Development genes and evolution, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
snail gene family members are zinc-finger transcription factors with key roles in morphogenesis. Involvement of snail family genes in mesoderm formation has been observed in insects and mammals. The snail genes are also involved in cell motility, neural differentiation, cell fate, survival decision, and left-right identity. The functions of snail genes have been studied primarily among ecdysozoans and deuterostomes, with relatively little work carried out in lophotrochozoans. In this study, we isolated two snail homologs (Hau-snail1 and Hau-snail2) from the leech Helobdella austinensis. We characterized the temporal and spatial expression patterns of these two genes by semi-quantitative RT-PCR and in situ hybridization. The expression of Hau-snail1 and Hau-snail2 correlates with ventral nerve cord (VNC) development, segmental mesoderm, and with a ring of cells that comes to lie at the base of the leech proboscis, respectively, showing similarity to the divergent expression of duplicated snail genes in polychaetes. Our results do not support the function of lophotrochozoan snail genes in mesoderm specification.
