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
Recombinant adenoviral vectors (AdVTNF-alpha) expressing alpha tumor necrosis factor (TNF-alpha) under control of cytomegalovirus (CMV) promoter have been used in cancer gene therapy. To reduce its cytotoxicity, we constructed a recombinant AdV(TERT)mTNF-alpha expressing a mutant TNF-alpha (mTNF-alpha) with mutations at D142N and A144R under control of human telomerase reverse transcriptase (hTERT) promoter for treatment of well-established ovalbumin (OVA)-expressing murine B16 melanoma (BL6-10(OVA)) (6 mm in diameter). We demonstrated that the mTNF-alpha with mutations at D142N and A144R has less in vitro cytotoxicity, but maintains its functional effect in the stimulation of T-cell proliferation. The in vitro and in vivo transgene expressions under control of hTERT promoter are highly restricted in tumor cells compared with those under the control of the CMV promoter. AdV(TERT)mTNF-alpha gene therapy by intratumoral injection of AdV(TERT)mTNF-alpha vector (2 x 10(9) PFU) expressing the mutant mTNF-alpha under control of hTERT promoter reduces its in vivo toxicity, eradicates well-established BL6-10(OVA) tumors in 4/10 tumor-bearing mice, and induces OVA-specific CD8(+) T-cell-mediated long-term antitumor immunity. Therefore, AdV(TERT)mTNF-alpha gene therapy may be very useful in the immunotherapy of cancer.
