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

purposeThe purpose of this study was to compare bacterial and polymeric gene delivery devices for the ability to deliver plasmid DNA to a murine macrophage P388D1 cell line.

methodsAn 85:15 ratio of poly(lactic-co-glycolic acid) (PLGA) and poly(beta-amino ester) polymers were formulated into microspheres that physically entrapped plasmid DNA encoding for the firefly luciferase reporter gene; whereas, the same plasmid was biologically transformed into a strain of Escherichia coli engineered to produce recombinant listeriolysin O. The two delivery devices were then tested for gene delivery and dosage effects using a macrophage cell line with both assays taking advantage of a 96-well high throughput format to quantify and compare each vector type.

resultsGene delivery was comparable for both vectors at higher vector dosages while lower dosages showed an improved delivery for the microsphere vectors. Delivery efficiency (defined as luciferase measurement/mg cellular protein/ng DNA delivered) was 881 luminescence mg(-1) ng(-1) for polymeric microspheres compared to 171 luminescence mg(-1) ng(-1) for the bacterial vectors.

conclusionA first head-to-head comparison between polymeric and bacterial gene delivery vectors shows a delivery advantage for polymeric microspheres that must also be evaluated in light of vector production, storage, and future potential.
