Comparison of plasmid DNA versus PCR amplified gene of insert DNA for nucleofection in Kasumi-1 cells.
Article in Cytotechnology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Plasmid electroporation, or its optimized version nucleofection, is an important technique for gene transfection of cells in suspension. However, substantial cell death and/or low transfection efficiency are still common for some cell lines. By using enhanced green fluorescent protein (EGFP) as a reporter, we compared the use of PCR amplified EGFP (PaEGFP) and its parental plasmid (pEGFP-N2) for nucleofection in Kasumi-1 cells. We found that PaEGFP induced significantly lower cell death but had similar transfection efficiency compared to its parent plasmid (pEGFP-N2). Most importantly, contrary to the pEGFP-N2-nucleofected cells, the PaEGFP-nucleofected cells subsequently grew properly. Tests in other cell lines also implied that PaEGFP indeed induced consistently less cell death, but transfection efficiencies varied, being good in suspension cell lines but lower in adhesive cell lines. We suggest that direct transfection with PCR amplified genes can be a simple and useful approach for optimization of electropulse-based transfection not only of Kasumi-1 cells, but also may be useful for other cell lines that are difficult to transfect in suspension.
