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
backgroundFibroblast activation protein-α (FAP) and livin α are considered as cancer-associated fibroblasts (CAFs) and tumor-specific targets, respectively, for immunogenic tumor vaccines. This study is designed to decipher the antitumor effect of double-gene modified dendritic cells (DCs) on Lewis lung carcinoma (LLC).
methodsBy encoding mouse FAP cDNA and human livin α (i.e., hlivin α) cDNA into recombinant adenoviral vector (rAd), rAd-FAP, rAd-hlivin α, and rAd-FAP/hlivin α were constructed, which were then transduced into mouse DCs. LLC-bearinig mice were immunized with the infected DCs (5 × 10
resultsDCs were successfully transduced with rAd-FAP/hlivin α in vitro. FAP was highly expressed in CAFs. CAFs were positive for α-SMA and negative for CD45 and CD31. Livin α level was upregulated in mouse LLC. Immunization with rAd-FAP/hlivin α-transduced DCs suppressed LLC volume and improved the survival of tumor-bearing mice. Immunization with rAd-FAP/hlivin α-transduced DCs enhanced the cytotoxic effect of splenic lymphocytes on LLC tumor-derived CAFs.
conclusionInjection with rAd-FAP/hlivin α-transduced DCs promotes immune-enhanced tumor microenvironment by decreasing CAFs and suppresses tumor growth in LLC mouse models.
