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

The complexity and diversity of proteoglycan structure means that they have a range of functions that regulate cell behavior. Through multiple interactions of their core proteins and glycosaminoglycans with extracellular matrix proteins, growth factors and chemokines, proteoglycans affect cell signaling, motility, adhesion, growth and apoptosis. Progressive changes in proteoglycans occur in the tumor microenvironment, but neither the source nor consequences of those changes are well understood. Proteoglycans studied in prostate cancer include versican--a hyalectan regulator of cell adhesion and migration-and the small leucine-rich proteoglycans decorin, biglycan and lumican, which have roles in cell signaling and tissue organization. Studies support an inhibitory role in prostate cancer for decorin and lumican. Conversely, the basement membrane proteoglycan perlecan might be a tumor promoter through upregulation of sonic hedgehog signaling. Loss of the growth-inhibitory cell-surface proteoglycans syndecan-1 and betaglycan in early prostate cancer might facilitate progression, but syndecan-1 effects are pleiotropic and its renewed expression in advanced tumors might adversely affect outcome. Importantly, cellular changes and enzymatic activity in the developing tumor can alter proteoglycan composition and structure to modify their function. Emerging studies suggest that cancers, including those of the prostate, use these changes to promote their own survival, growth, and spread.
