Growth of the Arabidopsis sub-epidermal integument cell layers might require an endosperm signal.
Article in Plant signaling & behavior, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
The seed, the reproductive unit of angiosperms, is physically protected by the seed coat. The seed coat develops from the ovule integuments after fertilization. The Arabidopsis ovule integuments are made of 5-6 cell layers of epidermal and sub-epidermal origin. The growth of the epidermal integument cell layers responds to an endosperm signal mediated by the AGAMOUS-LIKE 62 MADS box transcription factor with limited embryo contribution. By contrast, the sub-epidermal integument cell layers require the embryo to expand whereas the role of the endosperm is still unclear. Here, we analyzed the development of the sub-epidermal integument cell layers in agl62 mutant seeds, which undergo premature endosperm cellularization and arrest. Our data suggest that embryo and endosperm are both necessary to trigger the expansion of the sub-epidermal integument cell layers.
