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

Heteroduplex oligonucleotides (HDOs) are a novel type of oligonucleotide drugs based on the hybrid duplex between an antisense oligonucleotide (ASO) strand and its complementary RNA (cRNA) strand. HDOs were originally designed to enhance the pharmacokinetic properties of RNase H-dependent ASOs that carry ligand molecules on the cRNA strand. The first HDOs conjugated with α-tocopherol (toc-HDOs) demonstrated efficient silencing in various tissues and cells, including liver, endothelial cells in the brain, peripheral nerve, and immune cells. Cholesterol-conjugated HDOs (chol-HDOs) were shown to be efficiently delivered to the brain and to induce knockdown in brain cells. Furthermore, the HDO technology was found to be applicable to more than just gapmer-type oligonucleotides. The silencing efficiency of ASO-antimiRs based on LNA/DNA mixmers was improved, as were the pharmacokinetics of splicing-modulating PMOs by combining HDO formation with cholesterol. Therefore, HDO technology has been demonstrated to be a versatile platform for developing effective oligonucleotide therapeutics.
