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

CRISPR-Cas systems provide the small RNA-based adaptive immunity to defend against invasive genetic elements in archaea and bacteria. Organisms of Sulfolobales, an order of thermophilic acidophiles belonging to the Crenarchaeotal Phylum, usually contain both type I and type III CRISPR-Cas systems. Two species, Saccharolobus solfataricus and Sulfolobus islandicus, have been important models for CRISPR study in archaea, and knowledge obtained from these studies has greatly expanded our understanding of molecular mechanisms of antiviral defense in all three steps: adaptation, expression and crRNA processing, and interference. Four subtypes of CRISPR-Cas systems are common in these organisms, including I-A, I-D, III-B, and III-D. These cas genes form functional modules, e.g., all genes required for adaptation and for interference in the I-A immune system are clustered together to form aCas and iCas modules. Genetic assays have been developed to study mechanisms of adaptation and interference by different CRISPR-Cas systems in these model archaea, and these methodologies are useful in demonstration of the protospacer-adjacent motif (PAM)-dependent DNA interference by I-A interference modules and multiple interference activities by III-B Cmr systems. Ribonucleoprotein effector complexes have been isolated for Sulfolobales III-B and III-D systems, and their biochemical characterization has greatly enriched the knowledge of molecular mechanisms of these novel antiviral immune responses.
