The transcription factor IID subunit Taf13 is dispensable for TATA binding protein promoter recruitment and RNA polymerase II transcription.

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 multiprotein complex TFIID, comprising the TATA binding protein (TBP) and 13 TBP-associated factors (TAFs), is an essential component of the RNA polymerase II (Pol II) preinitiation complex (PIC). Cryo-electron microscopy studies suggested a critical role of the TAF11-TAF13 heterodimer in TBP promoter deposition upstream of the transcription start site. To investigate this hypothesis, we inactivated the gene encoding Taf13 in mice and embryonic stem cells (ESCs). Taf13-null embryos implant and survive until E6.5, but fail to undergo gastrulation, while Taf13-null ESCs are viable, but fail to form embryoid bodies and differentiate. Taf13 loss had little effect on TFIID integrity and led to only a mild reduction of TBP promoter recruitment, but led to altered PIC formation and globally reduced Pol II recruitment. Thus, the Taf11-Taf13 heterodimer is not essential for TBP/TFIID recruitment, revealing plasticity in the pathways of PIC formation.
