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

A family of generation 1, 2, and 3 triazine dendrimers differing in their core flexibility was prepared and evaluated for their ability to accomplish gene transfection. Dendrimers and dendriplexes were analyzed by their physicochemical and biological properties such as condensation of DNA, size, surface charge, morphology of dendriplexes, toxic and hemolytic effects, and ultimately transfection efficiency in L929 and MeWo cells. Flexibility of the backbone was found to play an important role with generation 2 dendrimer displaying higher transfection efficiencies than 25 kDa poly(ethylene imine) or SuperFect at a lower cytotoxicity level. This result is surprising, as PAMAM dendrimers require generations 4 or 5 to become effective transfection reagents. The ability to delineate effects of molecular structure and generation of triazine dendrimers with biological properties provides valuable clues for further modifying this promising class of nonviral delivery system.
