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 transcription factor TFII-I was initially isolated as a factor that can bind to initiator elements in core promoters. Recent evidence suggests that TFII-I may also have a role in signal transduction. We have found that overexpression of TFII-I can enhance the response of the wild-type c-fos promoter to a variety of stimuli. This effect depends on the c-fos c-sis-platelet-derived growth factor-inducible factor binding element (SIE) and serum response element (SRE). There is no effect of cotransfected TFII-I on the TATA box containing the c-fos basal promoter. Three TFII-I binding sites can be found in c-fos promoter. Two of these overlap the c-fos SIE and SRE, and another is located just upstream of the TATA box. Mutations that distinguish between serum response factor (SRF), STAT, and TFII-I binding to the c-fos SIE and SRE suggest that the binding of TFII-I to these elements is important for c-fos induction in conjunction with the SRF and STAT transcription factors. Moreover, TFII-I can form in vivo protein-protein complexes with the c-fos upstream activators SRF, STAT1, and STAT3. These results suggest that TFII-I may mediate the functional interdependence of the c-fos SIE and SRE elements. In addition, the ras pathway is required for TFII-I to exert its effects on the c-fos promoter, and growth factor stimulation enhances tyrosine phosphorylation of TFII-I. These results indicate that TFII-I is involved in signal transduction as well as transcriptional activation of the c-fos promoter.
