Characterization of extracellular proteases of Acanthamoeba genotype T4 isolated from different sources in Iran.
Article in Parasitology research, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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 members of the genus Acanthamoeba are ubiquitous, free-living amoebae found in various environments. The amoebae can cause severe complications in both, immunocompetent and immunocompromised individuals. The aim of this study was to characterize extracellular proteases of Acanthamoeba isolates from different sources belonging to genotype T4 as well as the determination of the pathogenicity potential to correlate pathogenicity with protease activity and protease banding pattern. A total of 19 isolates (11 clinical and 8 environmental) were cultured axenically, then the pathogenicity of the isolates was assessed by osmo- and thermo- tolerance tests. An applied colorimetric method using azocasein as a substrate was used for the extracellular protease activity assay. Protease characterization was carried out by zymography analysis with and without protease inhibitors. Assessment of the pathogenicity potential using physical parameters revealed that 2 (25%), 2 (25%), and 4 (50%) of the environmental isolates were potential pathogens, weak potential pathogens, and non-pathogens, respectively. According to our results, this protease activity assay can be a powerful tool for differentiating pathogenic and non-pathogenic strains of Acanthamoeba.
