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

High levels of foreign gene expression in mouse hepatocytes can be achieved by "hydrodynamics-based transfection," the rapid injection of a large volume of a naked deoxyribonucleic acid (DNA) solution into the tail vein. Rats are more tolerant of the frequent phlebotomies required for monitoring blood parameters than mice and, thus, are more suitable for some biomedical research. Recently, we demonstrated that hydrodynamics-based transfection can also be used to deliver naked plasmid DNA into the normal rat, which is more than 10 times larger than the mouse. We performed the tail vein injection using a syringe with a winged needle equipped with an external tube. Injection of a lac Z expression plasmid, pCAGGS-lac Z by this technique resulted in the exclusive detection of beta-galactosidase in the liver. We also injected a rat erythropoietin (Epo) expression plasmid, pCAGGS-Epo (800 microg). Maximal Epo gene expression was achieved when a 25-mL injection volume (approx 100 mL/kg body wt) was transferred within 15 s.
