A molecular and bioinformatic study on the ochratoxin A (OTA)-producing Aspergillus affinis (section Circumdati).
Article in Mycotoxin research, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Aspergillus affinis (section Circumdati) is a novel ochratoxin A (OTA)-producing species found in submerged riparian decomposing leaves. However, very little is known about its role on the breakdown of plant debris and its ability to degrade carbohydrate polymers. Moreover, its OTA biosynthetic pathway has not yet been explored. In the present paper, we investigated the gene encoding the extracellular alpha-amylase (amyAa) of A. affinis within the evolution of the Aspergillus lineages in relation to the possible use of this enzyme in starch processing. The novel amyAa, despite being related to branches of the Aspergillus species of the sections Terrei and Flavi, formed a distinct phylogenetic branch, which may be of outstanding importance from a biotechnological point of view. Moreover, we identified the polyketide synthase gene (pks) putatively required for the first step of OTA biosynthesis in A. affinis. This otapks was examined in relation to a limited number of orthologous genes available from Aspergillus species of the sections Circumdati and Nigri. Our study highlights the importance of otapks as target genes in the treatment of ochratoxigenic Aspergillus species on a more comprehensive evolutionary basis.
