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

In this study, we report that Streptomyces asterosporus DSM 41452 is a producer of new molecules related to the nonribosomal cyclodepsipeptide WS9326A and the polyketide annimycin. S. asterosporus DSM 41452 is shown to produce six cyclodepsipeptides and peptides, WS9326A to G. Notably, the compounds WS9326F and WS9326G have not been described before. The genome of S. asterosporus DSM 41452 was sequenced, and a putative WS9326A gene cluster was identified. Gene-deletion experiments confirmed that this cluster was responsible for the biosynthesis of WS9326A to G. Additionally, a gene-deletion experiment demonstrated that sas16 encoding a cytochrome P450 monooxygenase was involved in the synthesis of the novel (E)-2,3-dehydrotyrosine residue found in WS9326A and its derivatives. An insertion mutation within the putative annimycin gene cluster led to the production of a new annimycin derivative, annimycin B, which exhibited modest inhibitory activity against Plasmodium falciparum.
