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

purposeTargeting to antigen-presenting cells and efficient intracellular delivery of pDNA are essential for development of microsphere formulations of DNA vaccine.

methodsBiodegradable polymers containing acid-labile segments and galactose grafts were developed to entrap pDNA polyplexes into microspheres, which were proposed to promote transfection efficiency of pDNA.

resultsAcid-labile characteristics were approved by the hemolysis capabilities of red blood cells and degradation behaviors of matrix polymers; release of pDNA polyplexes from microspheres was significantly accelerated after incubation in acid buffers. Presence of galactose moieties enhanced cellular uptake of microspheres and increased acid-lability due to hydrophilic grafts on acid-labile segments. There was no apparent cytotoxicity of blank microspheres; cytotoxicity of pDNA polyplexes was significantly decreased after encapsulation into and sustained release from microspheres. High transfection efficiency and a dose-dependent transfection were indicated for pDNA polyplex-loaded acid-labile microspheres when balancing with cytotoxicity.

conclusionsIntegration of acid-lability, targeting effect into full biodegradable backbone represents an exciting approach to promote transfection efficiency through modulating release of pDNA polyplexes, targeting to antigen-presenting cells and intracellular delivery of pDNA.
