Protocol for enhancing Cas9 efficiency and fidelity through structure-guided phosphate-locking loop engineering.
Article in STAR protocols, 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
The phosphate-locking loop (PLL), stabilizing Cas9-DNA interactions, is a key target for optimizing efficiency and specificity. Here, we present a protocol for enhancing Cas9 efficiency and fidelity through structure-guided PLL engineering. We describe steps for identifying PLL engineering targets through sequence alignment and structural analysis, constructing variants via inverse PCR, evaluating efficiency using amplicon sequencing, and assessing specificity through Genome-wide Unbiased Identification of DSBs Evaluated by sequencing (GUIDE-seq (GUIDE-seq). This protocol provides a generalizable framework for Cas9 engineering across orthologs. For complete details on the use and execution of this protocol, please refer to Yang et al.
