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

Meroterpenoids are mixed polyketide-terpenoid natural products with a broad range of biological activities. Herein, we present the structures of four new meroterpenoid antibiotics, merochlorins A-D, produced by the marine bacterium Streptomyces sp. strain CNH-189, which possess novel chemical skeletons unrelated to known bacterial agents. Draft genome sequencing, mutagenesis, and heterologous biosynthesis in the genome-minimized model actinomycete Streptomyces coelicolor provided the 57.6 kb merochlorin gene cluster that contains two genes encoding rare bacterial vanadium-dependent haloperoxidase (VHPO) genes. Pathway expression of two different fosmid clones that differ largely by the presence or absence of the VHPO gene mcl40 resulted in the differential biosynthesis of merochlorin C, suggesting that Mcl40 catalyzes an unprecedented 15-membered chloronium-induced macrocyclization reaction converting merochlorin D to merochlorin C.
