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

The ability of reverse transcriptases (RTs) to synthesize a complementary DNA from natural RNA and a range of unnatural xeno nucleic acid (XNA) template chemistries, underpins key methods in molecular and synthetic genetics. However, RTs have proven challenging to discover and engineer, in particular for the more divergent XNA chemistries. Here we describe a general strategy for the directed evolution of RT function for any template chemistry called compartmentalized bead labelling and demonstrate it by the directed evolution of efficient RTs for 2'-O-methyl RNA and hexitol nucleic acids and the discovery of RTs for the orphan XNA chemistries D-altritol nucleic acid and 2'-methoxyethyl RNA, for which previously no RTs existed. Finally, we describe the engineering of XNA RTs with active exonucleolytic proofreading as well as the directed evolution of RNA RTs with very high complementary DNA synthesis fidelities, even in the absence of proofreading.
