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

We have evaluated the key properties of the polyethylenimine (PEI)-polyethylene glycol (PEG)-TAT peptide polyplex nanoparticles including their behavior in cells and compared them with the transfection efficacy (TE) using 11 different cell lines. We found statistically significant positive correlation between TE and the share of 50-75 nm fraction in the whole mixture of nanoparticles estimated with atomic force microscopy. Variations in PEG/PEI and N/P ratios (PEI nitrogen to DNA phosphate ratio) enabled us to find their optimal combinations, which resulted in up to 100% TE for several cell lines. Surfaces of the TE dependence of both PEG/PEI and N/P turned out to be similar in appearance for all investigated cell lines, while maximum TEs were different. We investigated subcellular transport kinetics and unpacking of the polyplex nanoparticles labeled with quantum dots (plasmid DNA) and AlexaFluor647 (block-copolymer part) using Förster Resonance Energy Transfer approach. The results demonstrated clear and statistically significant positive correlation of TE with the cellular uptake rate of the nanoparticles and negative correlation with the rate constant of their unpacking within endo/lysosomal compartments in the living cells.
