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

Prion diseases are infectious neurodegenerative disorders associated with the misfolded prion protein (PrP(Sc)), which appears to be the sole component of the infectious agent (termed prion). To produce disease, prions have to be absorbed into the body and reach sufficient quantities in the brain. Very little is known about the biological mechanisms controlling the initial fate of prions. Here, we studied the systemic pharmacokinetics and biodistribution of PrP(Sc) in vivo. After an intravenous injection of highly purified radiolabeled or native unlabeled PrP(Sc), the protein was eliminated rapidly from the serum (half-life of 3.24 h), mostly through tissue uptake. The quantity of intact PrP(Sc) reaching the brain was ∼ 0.2% of the injected dose per gram of brain tissue (ID/g). The highest levels were found in liver (∼ 20% ID/g), spleen (∼ 13% ID/g), and kidney (∼ 7.4% ID/g). Cell surface PrP(C) does not appear to play a role in PrP(Sc) pharmacokinetics, since the infectious protein distributed similarly in wild-type and PrP-null mice. To measure tissue uptake kinetics and biodistribution accurately, vascular space in tissues was measured with radioactively labeled albumin coinjected with radioactively labeled PrP(Sc). Our results provide a fundamental pharmacokinetic characterization of PrP(Sc) in vivo, which may be relevant to estimate tissue risks and mechanisms of prion neuroinvasion and to identify novel therapeutic strategies.
