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

In vitro protein production constitutes a valid resource to generate data regarding the structure and function of myosin 2. This technique can be combined with proteins, molecular complexes and small molecules to study myosin II conformation, binding to actin and the effect of various myosin and actin modulators. Here, we describe a straightforward protocol to produce and purify NM2 (non-muscle myosin 2) in Spodoptera frugiperda Sf9 cells. We also provide an example of produced protein use in an in vitro actin motility assay using TIRF microscopy to visualize myosin 2-driven F-actin motion and quantify it using ImageJ. This type of analysis can be implemented in various ways and become useful for drug screenings and characterization of novel, disease-causing mutations.
