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 delivery of the CRISPR/Cas ribonucleoprotein (RNP) has received attention for clinical applications owing to its high efficiency with few off-target effects. Lipid nanoparticles (LNPs) are potential non-viral vectors for the delivery of RNPs. Herein, we report the engineering of a branched scaffold structure of ionizable lipids for the hepatic delivery of RNPs. Both the total carbon number and branching position were critical for the functional delivery of RNPs. The optimal ionizable lipid exhibited a more than 98% reduction in transthyretin protein after a single dose with no obvious signs of toxicity. The mechanistic study has revealed that optimal LNPs have a unique "flower-like structure" that depends on both the lipid structure and the payload and that these LNPs accumulate in hepatocytes in an apolipoprotein E-independent manner. These results represent a major step toward the realization of
