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

Brain extracellular matrix (ECM) is highly degraded after cerebral ischemia. The perlecan c-terminal fragment LG3 is generated at increased levels by proteolytic processing as long as 3 days after ischemia. It has previously been shown that oxygen-glucose deprivation (OGD), reperfusion and interleukin-1 α (IL-1α) stimulate brain cells to yield increased levels of LG3. This LG3, in turn, is neuroprotective against OGD, and may therefore represent one of the brain's defenses against ischemic injury. Here, we investigate whether, in neurons, this increased LG3 is the result of increased perlecan generation and cellular release, increased protease release (to generate LG3 from previous extracellularly deposited perlecan) or both. We found that pre-synthesized perlecan may be exocytosed by neurons during OGD and de novo synthesis of perlecan is increased during reperfusion, even 24 h after OGD. Furthermore, while cathepsin L activity was seen to be marginally important to generate LG3 during normoxic conditions, cathepsin B activity was found to be important to generate increased levels of LG3 following OGD and reperfusion. On the other hand, IL-1α treatment raised levels of cathepsin L in neuronal media, and both cathepsin L and cathepsin B were demonstrated to be important for increasing LG3 levels after IL-1α treatment.
