Cell fate specification during respiratory development requires ARID1A-containing canonical BAF complex activity.

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
Mammalian lung development requires coordinated gene regulation to drive lung bud formation, branching morphogenesis, proximal-distal patterning, and epithelial specification. While key transcriptional and signaling regulators are known, the epigenetic regulators are less well studied. Here, we identify the canonical BAF complex as essential for lung epithelial development. Complete loss of BAF complex function causes failure of lung formation, and selective deletion of ARID1A leads to loss of distal patterning and reduced alveolar type 1 (AT1) cell differentiation, with emergence of a highly proliferative cell state defined by joint activation of YAP and WNT signaling and loss of BMP response. Epigenomic analyses demonstrate broad failure of cell type-specific enhancer activation. Notably, exogenous BMP4 rescues distal differentiation in embryonic murine lung organoids, while YAP and WNT signaling require functional BAF complex. These data demonstrate a requirement for BAF complex activity during lung epithelial development and reveal a surprising differential specificity between signaling pathways.
