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

Ionizable lipids largely determine the biocompatibility of lipid nanoparticles (LNPs) and the efficacy for mRNA delivery. Rational design and combinatorial synthesis have led to the development of potent and biodegradable ionizable lipids, yet methodologies for the stepwise optimization of ionizable lipid structure are lacking. Here we show that iterative chemical derivatization and combinatorial chemistry, and in particular the amine-aldehyde-alkyne coupling reaction, can be leveraged to iteratively accelerate the structural optimization of propargylamine-based ionizable lipids (named A
