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
To understand molecular mechanisms underlying wound-induced expression of plant peroxidase genes, the promoter of a horseradish C2 peroxidase (prxC2) gene was analyzed. We had previously isolated a tobacco nuclear protein, Ntlim1, as a trans factor binding to a PAL-box motif of the prxC2 promoter; however, the function of the Ntlim1 trans factor and the PAL-box motif in wound-responsive expression of the prxC2 gene remains unclear. Here, we found that the prxC2 promoter without the intact PAL-box motif failed to direct a normal level of both the basal and the wound-induced expression of beta-glucuronidase (GUS) reporter gene in transgenic tobacco plants, indicating that the PAL-box motif functions as an essential cis element of the prxC2 promoter. We also found that antisense expression of Ntlim1 in transgenic plants carrying the prxC2 promoter::GUS chimeric construct decreased not only the level of the basal and the wound-induced expression of the GUS reporter gene but also the extent of wound inducibility of the prxC2 promoter itself. This result indicates that Ntlim1 is required for the basal level of prxC2 promoter activity as well as its up-regulation under wound stress. Moreover, consistent with the results obtained in planta, result from super-shift assay indicates that the Ntlim1 binds to the PAL-box motif independently of wound stress.
