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

Base excision repair (BER) is a DNA repair pathway responsible for protecting the genome against modified nucleotides. DNA polymerase β (Pol β) participates in this process by removing the remnants of a damaged nucleotide and filling in the resulting gap. Pol β is overexpressed in some cancers and is synthetic lethal in cells deficient in BRCA1/2, providing additional impetus for identifying inhibitors of this enzyme. We report noncovalent Pol β inhibitors that are nonnative nucleotides. The inhibitors were identified via a combination of structural and biochemical analysis, as well as serendipity, from an initial library of covalent inhibitor candidates in which diversity was introduced sequentially at the C3'- and C5-positions of pyrimidine nucleotides. The molecules are among the most potent Pol β inhibitors (
