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

Bacterial secondary metabolites (SM) are rich sources of drug leads, and in particular, numerous metabolites have been isolated from actinomycetes. It was revealed by recent genome sequence projects that actinomycetes harbor much more secondary metabolite-biosynthetic gene clusters (SM-BGCs) than previously expected. Nevertheless, large parts of SM-BGCs in actinomycetes are dormant and cryptic under the standard culture conditions. Therefore, a widely applicable methodology for cryptic SM-BGC activation is required to obtain novel SM. Recently, it was discovered that co-culturing with mycolic-acid-containing bacteria (MACB) widely activated cryptic SM-BGCs in actinomycetes. This "combined-culture" methodology (co-culture methodology using MACB as the partner of actinomycetes) is easily applicable for a broad range of actinomycetes, and indeed, 33 novel SM have been successfully obtained from 12 actinomycetes so far. In this review, the development, application, and mechanistic analysis of the combined-culture method were summarized.
