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

Here we report in vitro selection of a novel ribozyme that catalyzes the 5'-nucleotidyl transfer reaction forming the 2'-5' phosphodiester bond. This ribozyme was retrieved as a sole sequence in the pool enriched for the 5'-triphosphate-dependent activities in incorporating ATP-gammaS. The originally selected ribozyme consisting of 109-nucleotide (nt) was miniaturized to 45-nt M4 ribozyme via a series of mutation studies, and based on this mini-ribozyme a trans-acting system was constructed. One of the most challenging tasks in our study was to determine the chemistry occurring at the 5'-ppp site. We utilized various analytical methods including MALDI-TOF analysis of the product generated by the trans-acting system and elucidated the chemistry to be 3'-->5' mononucleotide extension forming the 2'-5' phosphodiester bond. Interestingly, M4 ribozyme promiscuously accepts a variety of purine nucleotides bearing 5'-mono-, di- and triphosphates as substrates. This remarkable ability of M4 ribozyme would lead us to the development of a new tool for the 5'-modification of RNAs with unique chemical groups.
