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

Homologous recombination can be used to generate recombinants on episomes or directly on the Escherichia coli chromosome with PCR products or synthetic single-stranded DNA (ssDNA) oligonucleotides (oligos). Such recombination is possible because bacteriophage lambda-encoded functions, called Red, efficiently recombine linear DNA with homologies as short as 20-70 bases. This technology, termed recombineering, provides ways to modify genes and segments of the chromosome as well as to study homologous recombination mechanisms. The Red Beta function, which binds and anneals ssDNA to complementary ssDNA, is able to recombine 70-base oligos with the chromosome. In E. coli, methyl-directed mismatch repair (MMR) can affect these ssDNA recombination events by eliminating the recombinant allele and restoring the original sequence. In so doing, MMR can reduce the apparent recombination frequency by >100-fold. In the absence of MMR, Red-mediated oligo recombination can incorporate a single base change into the chromosome in an unprecedented 25% of cells surviving electroporation. Our results show that Beta is the only bacteriophage function required for this level of recombination and suggest that Beta directs the ssDNA to the replication fork as it passes the target sequence.
