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

CD147, also named extracellular matrix metalloproteinase inducer (EMMPRIN), has been shown to be involved in the progression of malignancy by regulating expression of vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs). The goal of this study was to evaluate the role of CD147 in the biology of bladder cancer and to determine its potential as a therapeutic target. CD147 protein expression was detected by immunohistochemistry in 108 bladder cancers using a tissue microarray annotated with patient follow-up. In immunohistochemistry, CD147 protein expression was associated with poor prognosis (P<0.001), lymph node status (P<0.001), tumor stage (P=0.003), histologic grade (P=0.011). Multivariate analysis showed that CD147 overexpression was an independent prognostic factor (P=0.019). Infection of T24 bladder cancer cells with an adenovirus that expressed a small interfering RNA (siRNA) against CD147 efficiently inhibited CD147 protein and mRNA expression. This resulted in decreased proliferation, soft agar colony formation, migration, and invasion of T24 cells in vitro. Moreover, downregulation of CD147 reduced secretion of MMP-2 and MMP-9 and expression of VEGF in these cells. Our findings suggest that CD147 overexpression plays an important role in progression of bladder cancer, and CD147 could be a potential target of bladder cancer therapy.
