High Fidelity Enzyme-Free Primer Extension with an Ethynylpyridone Thymidine Analog.
Article in Chemistry (Weinheim an der Bergstrasse, Germany), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
High fidelity base pairing is important for the transmission of genetic information. Weak base pairs can lower fidelity, complicating sequencing, amplification and replication of DNA. Thymidine 5'-monophosphate (TMP) is the most weakly pairing nucleotide among the canonical deoxynucleotides, causing high errors rates in enzyme-free primer extension. Here we report the synthesis of an ethynylpyridone C-nucleoside analog of 3'-amino-2',3'-dideoxythymidine monophosphate and its incorporation in a growing strand by enzyme-free primer extension. The ethynylpyridone C-nucleotide accelerates extension more than five-fold, reduces misincorporation and readily displaces TMP in competition experiments. The results bode well for the use of the C-nucleoside as replacements for thymidine in practical applications.
