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

Basement membranes are thin and dense proteinaceous layers that surround tissues to maintain their structure. With age, chronic inflammation typically stiffens this basement membrane through a phenomenon called fibrosis, which is reflected by increasing levels of the basement membrane's main structural component, type IV collagen (COL IV). Tissue fibrosis and elevated Notch signalling are two co-occurring hallmarks of many inflammation-linked diseases, including cancer, but their in vivo relationship has not been clearly defined. Here we show that EMB-9/COL IV accumulation around the C. elegans germline stem cell niche promotes GLP-1/Notch receptor activation in germline stem cells. Moreover, we find that contrasting with previous beliefs, reducing GLP-1/Notch activity in vivo leads to a generalized dramatic increase in EMB-9/COL IV levels, and thereby promotes fibrosis. The generalized fibrosis that comes along with inflammaging may therefore act as a root cause for cancer by promoting Notch signalling, and perhaps other ligand-receptor interactions.
