Chemical synthesis of long RNAs with terminal 5'-phosphate groups.
Article in Chemistry (Weinheim an der Bergstrasse, Germany), 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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.
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
Long structured RNAs are useful biochemical and biological tools. They are usually prepared enzymatically, but this precludes their site-specific modification with functional groups for chemical biology studies. One solution is to perform solid-phase synthesis of multiple RNAs loaded with 5'-terminal phosphate groups, so that RNAs can be concatenated using template ligation reactions. However, there are currently no readily available reagents suitable for the incorporation of the phosphate group into long RNAs by solid-phase synthesis. Here we describe an easy-to-prepare phosphoramidite reagent suitable for the chemical introduction of 5'-terminal phosphate groups into long RNAs. The phosphate is protected by a dinitrobenzhydryl group that serves as an essential lipophilic group for the separation of oligonucleotide by-products. The phosphate is unmasked quantitatively by brief UV irradiation. We demonstrate the value of this reagent in the preparation of a library of long structured RNAs that are site-specifically modified with functional groups.
