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

We introduce a family of protein nanoparticles capable of sensing analytes in conjunction with magnetic resonance imaging (MRI). The new sensors are derived from the iron storage protein ferritin (Ft); they are designed and optimized using facile protein engineering methods, and self-assembled in cells harboring specific combinations of DNA coding sequences. As illustration, we show that suitably constructed Ft-based sensors can report activity of the important neural signaling enzyme protein kinase A (PKA). Phosphorylation of the engineered Ft-based nanoparticles by PKA promotes clustering and changes in T(2)-weighted MRI signal.
