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

GalNAc oligonucleotide conjugates demonstrate improved potency in vivo due to selective and efficient delivery to hepatocytes in the liver via receptor-mediated endocytosis. GalNAc-siRNA and GalNAc-antisense oligonucleotides are at various stages of clinical trials, while the first two drugs were already approved by FDA. Also, GalNAc conjugates are excellent tools for functional genomics and target validation in vivo. The number of GalNAc residues in a conjugate is crucial for delivery as cooperative interaction of several GalNAc residues with asialoglycoprotein receptor enhances delivery in vitro and in vivo. Here we provide a robust protocol for the synthesis of triple GalNAc CPG solid support and GalNAc phosphoramidite, synthesis and purification of RNA conjugates with multiple GalNAc residues either to 5'-end or 3'-end and siRNA duplex formation.
