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

Terrestrial bacteria, especially actinomycetes, are known to be prolific producers of volatile compounds. We show here that bacteria from ocean sediments can also release complex bouquets of volatiles. The actinomycete Salinispora tropica produces cyclohexenyl compounds not previously known in nature, such as methyl cyclohex-2-ene-1-carboxylate (9), methyl 2-(cyclohex-2-en-1-yl)acetate (10), methyl (E/Z)-2-(cyclohex-2-en-1-ylidene)acetate (11/12), and related alcohols 8 and 13. These compounds were identified by GC/MS and confirmed by synthesis. In addition, rare spiroacetals, aromatic compounds, short-chain acids and esters, alcohols, and various cyclic compounds were produced by the bacteria. The biosynthesis of the cyclohexenyl compounds is closely coupled to that of cyclohexenylalanine (4), a building block of salinosporamide A, a proteasome inhibitor produced by S. tropica. Analysis of S. tropica strains that harbor knockouts of the salinosporamide biosynthetic genes salX and salD, coupled with feeding experiments, revealed that 3-(cyclohex-2-en-1-yl)-2-oxopropanoic acid (60) and 3-(cyclohex-2-en-1-ylidene)-2-oxopropanoic acid (isomers 61 and 62) are important intermediates in the biosynthesis of salinosporamide A, 4, and 8-13.
