Superpositioning of deletions promotes growth of Escherichia coli with a reduced genome.

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.
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
Escherichia coli has dispensable genome regions and eliminating them may improve cell use by reducing unnecessary metabolic pathways and complex regulatory networks. Although several strains with reduced genomes have already been constructed, there have been no reports of strains constructed with deletions assayed for influence on growth. To retain robust growth and fundamental metabolic pathways, the growth of each deletion strain and combination effects of deletions were checked using M9 minimal medium. Then a new strain, MGF-01, with a 1 Mb reduced genome was constructed by integrating deletions that did not affect growth. MGF-01 grew as well as the wild type in the exponential phase and continued growing after the wild type had entered the stationary phase. The final cell density of MGF-01 was 1.5 times higher than that of the wild-type strain. Using MGF-01 as a production host, a 2.4-fold increase in l-threonine production was achieved.
