Directional motion of foreign plasmid DNA to nuclear HP1 foci.

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
Movement of labelled plasmid DNA relative to heterochromatin foci in nuclei, visualized with HP1-GFP, was studied using live-cell imaging and object tracking. In addition to Brownian motion of plasmid DNA we found a pronounced, non-random movement of plasmid DNA towards the nearest HP1 focus, while time-lapse microscopy showed that HP1 foci are relatively immobile and positionally stable. The movement of plasmid DNA was much faster than that of the HP1 foci. Contact of transgene DNA with an HP1 focus usually resulted in cessation of the directional motion. Moreover, the motion of plasmid DNA inside the heterochromatin compartment was more restricted (limited to 0.25 microm) than when the plasmid DNA was outside heterochromatin (R = 0.7 microm). Three days after transfection most of the foreign labelled DNA colocalized with centromeric heterochromatin.
