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
Lung cancer remains among the most difficult-to-treat malignancies and is the leading cause of cancer-related deaths worldwide. The introduction of targeted therapies and checkpoint inhibitors has improved treatment outcomes; however, most patients with advanced-stage non-small cell lung cancer (NSCLC) eventually fail these therapies. Therefore, there is a major unmet clinical need for checkpoint refractory/resistant NSCLC. Here, we tested the combination of aPD-1 and adenovirus armed with TNFα and IL-2 (Ad5-CMV-mTNFα/mIL-2) in an immunocompetent murine NSCLC model. Moreover, although local delivery has been standard for virotherapy, treatment was administered intravenously to facilitate clinical translation and putative routine use. We showed that treatment of tumor-bearing animals with aPD-1 in combination with intravenously injected armed adenovirus significantly decreased cancer growth, even in the presence of neutralizing antibodies. We observed an increased frequency of cytotoxic tumor-infiltrating lymphocytes, including tumor-specific cells. Combination treatment led to a decreased percentage of immunosuppressive tumor-associated macrophages and an improvement in dendritic cell maturation. Moreover, we observed expansion of the tumor-specific memory T cell compartment in secondary lymphoid organs in the group that received aPD-1 with the virus. However, although the non-replicative Ad5-CMV-mTNFα/mIL-2 virus allows high transgene expression in the murine model, it does not fully reflect the clinical outcome in humans. Thus, we complemented our findings using NSCLC ex vivo models fully permissive for the TNFα and IL-2- armed oncolytic adenovirus TILT-123. Overall, our data demonstrate the ability of systemically administered adenovirus armed with TNFα and IL-2 to potentiate the anti-tumor efficacy of aPD-1 and warrant further investigation in clinical trials.
