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

Bacterial Type IV CRISPR-Cas systems are thought to rely on multi-subunit ribonucleoprotein complexes to interfere with mobile genetic elements, but the substrate requirements and potential DNA nuclease activities for many systems within this type are uncharacterized. Here we show that the native Pseudomonas oleovorans Type IV-A CRISPR-Cas system targets DNA in a PAM-dependent manner and elicits interference without showing DNA nuclease activity. We found that the first crRNA of P. oleovorans contains a perfect match in the host gene coding for the Type IV pilus biogenesis protein PilN. Deletion of the native Type IV CRISPR array resulted in upregulation of pilN operon transcription in the absence of genome cleavage, indicating that Type IV-A CRISPR-Cas systems can function in host gene regulation. These systems resemble CRISPR interference (CRISPRi) methodology but represent a natural CRISPRi-like system that is found in many Pseudomonas and Klebsiella species and allows for gene silencing using engineered crRNAs.
