Screening of Antibiotic Gene Clusters in Microorganisms Isolated from Wood.
Article in Methods in molecular biology (Clifton, N.J.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
The biosphere of Earth is made up of a variety of ecosystems governed by complex biological interactions, some of them mediated by microbial bioactive secondary metabolites. These metabolites such as antibiotics (e.g., polyketides and nonribosomal peptides) have been receiving increasing attention, due to their multiple pharmaceutical uses. Besides, antibiotic resistance is on the rise, and it is currently regarded as one of the greatest threats to global human health. The screening of novel antimicrobial polyketides and nonribosomal peptides in poorly studied ecosystems is an interesting alternative to address the problem of antibiotic resistance. This chapter updates a molecular method to identify antibiotics gene clusters and their subsequent production and activity validation. On the one hand, a PCR method based on degenerated primers for nonribosomal peptide synthases (NRPS) and the polyketide synthases (PKS) genes is used as an initial fast screening. On the other hand, a bioassay-based method is the protocol selected for the production confirmation and antibacterial effect estimation. These methods are applied to screen Actinobacteria and Penicillium species as main antibiotic producers isolated from wood.
