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
CRISPR/Cas9 and Cas12a belonging to the Class II CRISPR system are characterized by a single-component effector protein. Despite unique features of Cas12a like DNA cleavage with 5' staggered ends and a single crRNA, Cas12a has not been adopted in biotechnological applications to the similar extent as Cas9. To better understand the CRISPR/Cas12 systems, we selected two candidates, designated mgCas12a-1 and mgCas12a-2, from an analysis of the human microbiome metagenome (mg) and provided biochemical characterization. These new Cas12a proteins shared about 37% identity in amino acid sequences and shared the same direct repeat sequences in the crRNA with FnCas12a from Francisella novicida. The purification yield of the recombinant proteins was up to 3.6-fold greater than that of FnCas12a. In cell-free DNA cleavage assays, both mgCas12a proteins showed the higher cleavage efficiencies when Mn
