Molecular basis of target RNA cleavage by Cas13.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
RNA-targeting CRISPR-Cas13 enzymes are robust RNA knockdown tools with both on-target and collateral cleavage activities. However, to date, the in vivo RNA cleavage mechanisms remain poorly understood. Here, we combine in vitro and in vivo methods to elucidate the exact cleavage sites of Cas13. We reveal that some subtypes of Cas13, including Cas13b and Cas13bt, cleave the target RNA at predominant positions, and rational engineering of Cas13 further improves precision. Building on these findings, we develop RNA segment editing (RSE), a targeted RNA cleavage and repair method, to restore dysfunctional RNA in cells. We anticipate that RSE will enable precision RNA engineering for therapeutics and basic research.
