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
Fibulin 2 (FBLN2) is an extracellular matrix glycoprotein. Exclusion of exon 9 of FBLN2 is one of the most recurrent splicing events across multiple types of cancer, but its functional relevance in cancer has remained unexplored. We here reveal that the exclusion of exon 9 of FBLN2 results in the loss of a single N-glycosylation site that leads to misfolding of the FBLN2 protein as well as to a reduction in both its stability and secretion efficiency. Indeed, the extracellular matrix of human colorectal cancer tissue exhibits a reduced abundance of FBLN2. This deficiency of FBLN2 together with a concomitant increase in the abundance of fibronectin 1 in the tumor microenvironment promotes the adhesion and migration of colorectal cancer cells. Our data thus suggest that the alternative splicing of FBLN2 exon 9 generates a prometastatic extracellular environment in cancer tissue by determining FBLN2 glycosylation.
