Direct Observation of Archaellar Motor Rotation by Single-Molecular Imaging Techniques.

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.
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
Single-molecular techniques have characterized dynamics of molecular motors such as flagellum in bacteria and myosin, kinesin, and dynein in eukaryotes. We can apply these techniques to a motility machine of archaea, namely, the archaellum, composed of a thin helical filament and a rotary motor. Although the size of the motor hinders the characterization of its motor function under a conventional optical microscope, fluorescence-labeling techniques allow us to visualize the architecture and function of the archaellar filaments in real time. Furthermore, a tiny polystyrene bead attached to the filament enables the visualization of motor rotation through the bead rotation and quantification of biophysical properties such as speed and torque produced by the rotary motor imbedded in the cell membrane. In this chapter, I describe the details of the above biophysical method based on an optical microscope.
