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

Oxidative stress induces damage to DNA, RNA, and nucleotide pools. Unlike well-studied DNA damage, the formation of RNA damage and the impact of an oxidized ribonucleotide pool on transcription fidelity are poorly understood. Here, we investigate the structural basis of transcription-coupled RNA damage and the effect of 8-oxo-guanosine triphosphate (8-oxo-rGTP) on RNA polymerase II (Pol II) transcription fidelity control steps. We revealed that the incorporation efficiency of 8-oxo-rGTP opposite a dC template is comparable to that of GTP. In contrast, the incorporation efficiency of 8-oxo-rGTP opposite a dA template is ~150-fold more efficient than that of GTP. For the extension step, Pol II extends substantially faster from a 3'-8-oxo-rG:dC base pair than from a 3'-8-oxo-rG:dA base pair. For the proofreading step, strikingly, Pol II EC with 3'-8-oxo-rG:dA base pair is much more resistant to backtracking and proofreading than Pol II EC with 3'-8-oxo-rG:dC base pair. Using X-ray crystallography, we revealed that 8-oxo-rGTP adopts different prechemistry binding sites depending on whether it is paired with a dC or a dA template. Upon incorporation, the nucleobase of 8-oxo-rG flips to the
