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

A comparative genomic approach was used to identify Helicobacter pylori 26695 open reading frames (ORFs) which are conserved in H. pylori J99 but highly diverged in other eubacteria. A survey of selected pathways of central intermediary metabolism was also carried out, and genes with a potentially selective role in H. pylori were identified. Forty-five ORFs identified in these two analyses were screened using a rapid vector-free allelic replacement mutagenesis technique, and 33 were shown to be essential in vitro. Notably, 13 ORFs gave essentiality results which are unexpected in view of their known or proposed functions, and phylogenetic analysis was used to investigate the annotation of 7 such ORFs which are highly diverged. We propose that the products of a number of these H. pylori-specific essential genes may be suitable targets for novel anti-H. pylori therapies.
