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 present study was conducted to identify the anti-tumor effects of rAd/p53, which is a recombinant human serotype 5 adenovirus, in cutaneous squamous cell carcinoma (cSCC). Mouse models of human cSCC were constructed by injecting human cutaneous squamous cell carcinoma cells into both flanks of nude mice. Subsequently, the 75 nude mice with cSCC xenograft tumors were randomly divided into recombinant human serotype 5 adenovirus (rAd)/p53, rAd/p53 + 5-fluorouracil (5-Fu) and 5-Fu groups. One side of the tumors was administered the therapeutic agents as the therapeutic group, whereas the remaining side was treated with medical saline as the control. At 24, 48, 72, 120 and 168 h post-intratumoral injection, alterations in tumor volume, tumor necrosis and the expression of several tumor-associated genes, including Smad4, Brca1 and matrix metalloproteinase (MMP-2), were analyzed. Compared with its control group, the rAd/P53 group exhibited a significantly increased tumor necrosis ratio. In addition, Smad4 and Brca1 expression levels increased significantly at various time points (P<0.05), and MMP-2 expression decreased significantly (P<0.05). In the rAd/p53 + 5-Fu group, the tumor necrosis ratio, and Smad4 and Brca1 expression levels also significantly increased at various time points (P<0.05). MMP-2 gene transcription gradually decreased, high expression of Smad4 was prolonged, and high expression of Brca1 was observed in the early period following treatment compared with the rAd/P53 group. In addition, p53 expression exhibited a positive correlation with the tumor necrosis ratio and Smad4 expression, and showed a negative correlation with MMP-2 gene transcription (P<0.05). These findings indicate that rAd/p53 has a potent anti-tumor effect in cSCC via the promotion of tumor necrosis and regulating the expression of various tumor-associated genes.
