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

An efficient non-viral gene delivery for varieties of cells has been considered essential for gene therapy and tissue engineering. This study evaluated transfection efficiency of chitosan (HW) with molecular weights (Mw) at 470 and degree of deacetylation (DDA) 80% and its depolymerization product (LW) with Mw at 16 kDa and DDA 54%, as well as epidermal growth factor (EGF) conjugated to chitosan-DNA microparticles of both HW and LW by using either disulfide linkage or NHS-PEO(4)-Maleimide as a cross linker. The results revealed that the depolymerized LW at chitosan/DNA charge ratio 56:1 and pH 6.9 gave high transfection efficiency in both KB, a cancer cell line, and fibroblast cells at about the same level of Lipofectamine, but the EGF-conjugated chitosan-DNA polyplexes from these methods did not improve transfection efficiency, which may come from the aggregation and fusing of the complexes as shown in scanning electron microscopy. However, this depolymerized LW chitosan showed the potential for further development as a safe and cost-effective non-viral gene delivery vehicle.
