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

Topoisomerases unlink chromosomes and relieve topological stress. Topoisomerase "poisons" are widely used chemotherapeutics that stabilize topoisomerase complexes on DNA, leading to cytotoxic DNA breaks and cancer cell killing. It is well established that topoisomerase poisons interfere with DNA replication, which is thought to be a major physiological target of these drugs. However, many questions remain about the mechanisms by which topoisomerase poisons impact DNA replication and the downstream consequences. Here, we describe assays to study topoisomerase poisons during vertebrate DNA replication using Xenopus egg extracts. These approaches allow for replication intermediates formed following poison treatment to be carefully monitored with high temporal resolution.
