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
Yeast mRNA 5'-triphosphatase, Cet1p, recognizes phosphorylated-RNA polymerase II as a component of capping machinery via Ceg1p for cotranscriptional formation of mRNA cap structure that recruits cap-binding complex (CBC) and protects mRNA from exonucleases. Here, we show that the accumulation of RNA polymerase II at the promoter proximal site of ADH1 is significantly enhanced in the absence of Cet1p. Similar results are also found at other genes. Cet1p is recruited to the 5' end of the coding sequence, and its absence impairs mRNA capping, and hence CBC recruitment. However, such an impaired recruitment of CBC does not enhance promoter proximal accumulation of RNA polymerase II. Thus, Cet1p specifically lowers the accumulation of RNA polymerase II at the promoter proximal site independently of mRNA cap structure or CBC. Further, we show that Cet1p's N-terminal domain, which is not involved in mRNA capping, decreases promoter proximal accumulation of RNA polymerase II. An accumulation of RNA polymerase II at the promoter proximal site in the absence of Cet1p's N-terminal domain is correlated with reduced transcription. Collectively, our results demonstrate a novel role of Cet1p in regulation of promoter proximal accumulation of RNA polymerase II independently of mRNA capping activity, and hence transcription in vivo.
