1 · What the graph read from it

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.

2 · The registry

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

Cancer-associated fibroblasts (CAFs) play a crucial role in collagen accumulation, which develops and promotes peritoneal metastasis (PM) in gastric cancer (GC). In addition, the abundant stromal collagens in the tumor microenvironment function as a physical barrier against penetration of antitumor drugs and oncolytic viruses. This study investigated whether collagen depletion by pirfenidone (PFD), an antifibrotic drug, enhances the antitumor effects of oncolytic adenoviruses. Analysis of the clinical samples revealed a significant association of high expression of collagen 1 and α-smooth muscle actin (α-SMA) with PM development and poor prognosis of advanced GC. Human and murine GC cells enhanced collagen production by fibroblasts, which was suppressed by PFD. Abundant fibroblasts and collagen inhibited the penetration of OBP-702, which reduced the antitumor effects of OBP-702 in the spheroid model. Intraperitoneal co-injection of GC cells and fibroblasts promoted the development of collagen-rich PM and reduced the antitumor effects of OBP-702
