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

Adaptive immunity of prokaryotes is mediated by CRISPR-Cas systems that employ a large variety of Cas protein effectors to identify and destroy foreign genetic material. The different targeting mechanisms of Cas proteins rely on the proper protection of the host genome sequence while allowing for efficient detection of target sequences, termed protospacers. A short DNA sequence, the protospacer-adjacent motif (PAM), is frequently used to mark proper target sites. Cas proteins have evolved a multitude of PAM-interacting domains, which enables them to cope with viral anti-CRISPR measures that alter the sequence or accessibility of PAM elements. In this review, we summarize known PAM recognition strategies for all CRISPR-Cas types. Available structures of target bound Cas protein effector complexes highlight the diversity of mechanisms and domain architectures that are employed to guarantee target specificity.
