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
Caudal‑related homeobox transcription factor 2 (CDX2) is a transcription factor, which is specifically expressed in the adult intestine. It is essential for the development and homeostasis of the intestinal epithelium and its functions as a tumor suppressor have been demonstrated in the adult colon. The present study aimed to examine the inhibitory effects of the overexpression of CDX2 on subcutaneously‑transplanted tumors, derived from LoVo colon cancer cells, in nude mice, and to provide experimental evidence for the biotherapy of colon cancer. A pEGFP‑C1‑CDX2 eukaryotic expression vector was transfected into the LoVo cells via lipofection, and LoVo cells stably‑expressing CDX2 (pEGFP‑C1‑CDX2 cells) were obtained using G418 selection. A nude mouse subcutaneously‑transplanted tumor model was established by inoculating the nude mice with the pEGFP‑C1‑CDX2 cells, and the effects of overexpression of CDX2 on transplanted tumor growth in the LoVo cells were observed. Western blotting results demonstrated that the protein expression of CDX2 in the LoVo cells was higher in the pEGFP‑C1‑CDX2 cell group, compared with that in the pEGFP‑C1 cell group and the untreated cell group. At 20 days post‑inoculation with either pEGFP‑C1‑CDX2 or pEGFP‑C1, the transplanted tumor masses were significantly lower in the pEGFP‑C1‑CDX2 group, compared with those in the pEGFP‑C1 and untreated groups. Immunohistochemistry revealed that the expression levels of CDX2 and matrix metalloproteinase‑2 (MMP‑2) were detected in each group, and the protein expression of CDX2 was increased in the tumor tissues from the nude mice in the pEGFP‑C1‑CDX2 group. However the expression of MMP‑2 was downregulated in the tumor tissues of the nude mice in the pEGFP‑C1‑CDX2 group. Taken together, these data suggested that pEGFP‑C1‑CDX2 cells exhibited suppressed tumor growth in vivo. Overexpression of CDX2 was observed in transplanted tumors in the pEGFP‑C1‑CDX2 group, and the gene expression of MMP‑2 was reduced. These results indicate that CDX2 inhibited the growth of colorectal tumor cells, possibly by downregulating the gene expression.
