BRD4 promotes endodermal cell fate during mammalian lung development.

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
Lung development relies on diverse cell intrinsic and extrinsic mechanisms to ensure proper cellular differentiation and compartmentalization. In addition, it requires precise integration of multiple signaling pathways to temporally regulate morphogenesis and appropriate cell specification. To accomplish this, organogenesis relies on epigenetic and transcriptional regulators to promote cell fate and inhibit alternative cell fates. Using genetic mouse and human embryonic stem cell (hESC) differentiation models, tissue explants, and single-cell transcriptomic analysis, we demonstrated that Bromodomain Containing Protein 4 (BRD4) is required for mammalian lung morphogenesis and cell fate. Endodermal deletion of BRD4 impaired epithelial-mesenchymal crosstalk, leading to disrupted proximal-distal patterning and branching morphogenesis. Moreover, temporal deletion of BRD4 revealed developmental stage-specific defects in airway and alveolar epithelial cell specification with a predominant role in proximal airway cell fate. Similarly, BRD4 promoted lung endodermal cell differentiation into airway lineages in a hESC-derived lung organoid model. Together, these data demonstrate that BRD4 orchestrates early lung morphogenesis and separately regulates cell specification, indicating a multifunctional and evolutionarily conserved role for BRD4 in mammalian lung development.
