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

Bacteria are indispensable for the study of fundamental molecular biology processes due to their relatively simple gene and genome architecture. The ability to engineer bacterial chromosomes is quintessential for understanding gene functions. Here we demonstrate the engineering of the small-ribosomal subunit (16S) RNA of Mycoplasma mycoides, by combining the CRISPR/Cas9 system and the yeast recombination machinery. We cloned the entire genome of M. mycoides in yeast and used constitutively expressed Cas9 together with in vitro transcribed guide-RNAs to introduce engineered 16S rRNA genes. By testing the function of the engineered 16S rRNA genes through genome transplantation, we observed surprising resilience of this gene to addition of genetic elements or helix substitutions with phylogenetically-distant bacteria. While this system could be further used to study the function of the 16S rRNA, one could envision the "simple" M. mycoides genome being used in this setting to study other genetic structures and functions to answer fundamental questions of life.
