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

The bacterial backbone (BB) sequences contained within a canonical plasmid DNA dampen exogenous transgene expression by tenfold to 1,000-fold over a period of a few weeks following transfection into quiescent tissues such as the liver. Minicircle DNA vectors devoid of bacterial plasmid backbone sequences overcome transgene silencing providing persistent transgene expression. Because, we recently established that the length rather than sequence of the DNA flanking the transgene expression cassette is the major parameter affecting transgene silencing, we developed an alternative plasmid propagation process in which the essential bacterial elements for plasmid replication and selection are placed within an engineered intron contained within the eukaryotic expression cassette. As with the minicircle vector, the mini-intronic plasmid (MIP) vector system overcomes transgene silencing observed with plasmids but in addition provides between 2 and often 10 times or higher levels of transgene expression compared with minicircle vectors containing the same expression cassette in vivo and in vitro. These improved plasmids will benefit all studies involving gene transfer/therapy approaches.
