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 BRG-/BRM-associated factor (BAF) chromatin remodeling complex is a central actor in transcription. One mechanism by which BAF affects gene expression is via its various histone mark readers, including double plant homeodomains (DPF), located in the BAF45D subunit. DPF domains recognize lysine acetyl and acylations, including crotonylation, localized at promoters and enhancers. Despite a significant degree of conservation between DPF domains, attempts to crystallize BAF45D with a crotonylated histone 3 peptide (H3K14Cr) were unsuccessful. In addition, recent cryoEM and modeled structures failed to define the Req domain of BAF45D, which is responsible for reading lysine modifications. Thus, the precise mechanism of crotonyl group recognition and binding by BAF45D within the BAF complex remains unclear. We turned to protein footprinting mass spectrometry to map the binding interface between H3K14Cr and BAF45D. This technique is able to demarcate protein-binding interfaces by modifying surface-accessible residues and is not limited by protein size or composition.
