Enzymatic and Antimicrobial Activities in Polar Strains of Microscopic Soil Fungi.

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
Potential to produce inducible enzymes (several hydrolases and oxidases) and antibiotics as secondary metabolites was studied in soil micromycete strains from the Arctic (Franz Josef Land and Novaya Zemlya) and Antarctica (the oases Thala Hills, Larsemann Hills, Schirmacher, and Marie Byrd Land). Maximal esterase activity was observed in strains of two typical Antarctic species, Hyphozyma variabilis 218 and Thelebolus ellipsoideus 210 (51 and 29 nmol FDA/((g mycelium h), respectively). Cellulolytic activity was maximal (89 µmol glucose/mg biomass) in Ascochyta pisi 192. Extracellular phenol oxidase (laccase) and peroxidase activities were not detected in the strains examined. Antibacterial activity toward Bacillus subtilis ATCC 6633 was observed in 75% of the Antarctic micromycete strains. Higher-activity strains were isolated from organic-rich moist habitats with a moss or lichen cover. Maximal activities were displayed by Paecilomyces marquandii 166, Penicillium janczewskii 165, Penicillium roseopurpureum 169, and Thelebolus ellipsoideus 210. Antagonistic activity toward Antarctic bacterial strains was shown by 77% of the microfungal strains examined. Maximal inhibition was observed with strains of the typical Antarctic species Antarctomyces psychrotrophicus MT303855 and the eurytopic species Sarocladium kiliense MT303856. Antimycotic activity was observed in 42% of the strains. Both activities were detected in 38% of the Antarctic strains.
