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
Plasmids are one of the most important genetic tools for basic research and biotechnology, as they enable rapid genetic manipulation. Here we present a novel pBBR1-based plasmid for Methylorubrum extorquens, a model methylotroph that is used for the development of C1-based microbial cell factories. To develop a vector with compatibility to the so far mainly used pCM plasmid system, we transferred the pBBR1-based plasmid pMiS1, which showed an extremely low transformation rate and caused a strong growth defect. Isolation of a suppressor mutant with improved growth led to the isolation of the variant pMis1_1B. Its higher transformation rate and less pronounced growth defect phenotype could be shown to be the result of a mutation in the promotor region of the rep gene. Moreover, cotransformation of pMis1_1B and pCM160 was possible, but the resulting transformants showed stronger growth defects in comparison with a single pMis1_1B transformant. Surprisingly, cotransformants carrying pCM160 and a pMis1_1B derivative containing a mCherry reporter construct showed higher fluorescence levels than strains containing only the pMis1_1B-based reporter plasmids or a corresponding pCM160 derivative. Relative plasmid copy number determination experiments confirmed our hypothesis of an increased copy number of pMis1_1B in the strain carrying both plasmids. Despite the slight metabolic burden caused by pMis1_1B, the plasmid strongly expands the genetic toolbox for M. extorquens.
