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

Phage λ-Red proteins are powerful tools for pulling and knocking out chromosomal fragments but have been limited to the γ-proteobacteria. Procedures are described here to easily knock out (KO) and pull out (PO) chromosomal DNA fragments from naturally transformable Burkholderia thailandensis and Burkholderia pseudomallei. This system takes advantage of published compliant counterselectable and selectable markers (sacB, pheS, gat and the arabinose-utilization operon) and λ-Red mutant proteins. pheS-gat (KO) or oriT-ColE1ori-gat-ori1600-rep (PO) PCR fragments are generated with flanking 40- to 45-bp homologies to targeted regions incorporated on PCR primers. One-step recombination is achieved by incubation of the PCR product with cells expressing λ-Red proteins and subsequent selection on glyphosate-containing medium. This procedure takes ~10 d and is advantageous over previously published protocols: (i) smaller PCR products reduce primer numbers and amplification steps, (ii) PO fragments suitable for downstream manipulation in Escherichia coli are obtained and (iii) chromosomal KO increases flexibility for downstream processing.
