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 developed a simple and rapid method for constructing knockout vectors using inverse-PCR (IPCR). The method consists of three steps: (i) digestion of a target bacterial artificial chromosome with several restriction enzymes (six-base cutters) followed by self-ligation; (ii) IPCR using circular DNAs as templates and two primers which are oriented in opposite directions; and (iii) cloning into a vector containing a positive selection marker, which results in a typical replacement knockout vector. We successfully targeted three mouse genes including the HPRT gene using this method. Compared with the conventional method, this method requires much less time (no more than 3 weeks). Notably, this method requires only small amounts of sequence information (several hundred base pairs such as is available from expressed sequence tags) and can be extended to a systematic mass production of targeting vectors applicable to many organisms, including yeast.
