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

DNA in most bacterial cells is maintained in an underwound state. The DNA double helix responds to underwinding by adopting a minimum energy conformation through the supercoiling of the duplex, the formation of local single-stranded bubbles or a combination of both. This Microbiology Primer summarizes the key topological features of DNA and describes the topoisomerase enzymes that manage bacterial DNA topology. The influences of variable DNA topology on transcription and of transcription (and DNA replication) on DNA topology are also discussed. Finally, the article considers the impact of changes in bacterial metabolism and physiology on DNA topology and their implications for bacterial pathogenesis.
