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

Cre-mediated recombination is a widely used technique for the re-arrangement of DNA sequences that are bracketed by loxP recognition sites. This bacteriophage P1 enzyme is commonly used to excise the bacterial artificial chromosome (BAC) sequence, a vector sequence used for large herpesvirus genomes for the purposes of propagation and manipulation in Escherichia coli. Most methods utilize cell lines that can be induced for the expression of Cre enzyme to facilitate this excision. In addition, methods have been developed that express Cre from the virus genome and enable auto-excision of the BAC plasmid. We report a versatile and rapid in vitro method based on purified Cre enzyme to carry out the same process in a test tube and does not require cell line generation or cloning into the virus genome. This method greatly increases the repertoire of methods available to modify the genome prior to reconstitution of virus infectivity in a mammalian host.
