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

Two RNA fragments linked by means of a 2',5' phosphodiester bridge (2' hydroxyl of one fragment connected to the 5' hydroxyl of the other) constitute a class of nucleic acids known as 2'-5' branched RNAs (bRNAs). In this report we show that bRNA analogues containing 2'-5' phosphoramidate linkages (bN-RNAs) inhibit the lariat debranching enzyme, a 2',5'-phosphodiesterase that has recently been implicated in neurodegenerative diseases associated with aging. bN-RNAs were efficiently generated using automated solid-phase synthesis and suitably protected branchpoint building blocks. Two orthogonally removable groups, namely the 4-monomethoxytrityl (MMTr) group and the fluorenylmethyl-oxycarbonyl (Fmoc) groups, were evaluated as protecting groups of the 2' amino functionality. The 2'-N-Fmoc methodology was found to successfully produce bN-RNAs on solid-phase oligonucleotide synthesis. The synthesized bN-RNAs resisted hydrolysis by the lariat debranching enzyme (Dbr1) and, in addition, were shown to attenuate the Dbr1-mediated hydrolysis of native bRNA.
