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

backgroundHuman skin is naturally exposed to diverse fungi. New taxa, including species with unknown pathogenic potential, continue to be isolated from human skin.

objectiveTo characterize a hitherto unknown hyphomycete isolated from human eczema and to assess its habitat and pathogenic abilities.

methodsA broad panel of culture conditions was used for morphological examination and physiological testing. Nucleotide ribosomal ITS and LSU sequences were analyzed separately by BLASTn to identify the closest relatives, and a combined ITS-LSU dataset was used for phylogenetic inference.

resultsThe isolate grew well on common mycological agars at 26°C and was not inhibited by 0.4 g/L cycloheximide. Colonies were flat, with a beige obverse and sparse aerial mycelium. Intercalary, round to subglobose spores developed within the hyphae, and submerged hyphae in cultures older than 4 weeks transformed into chains of spores consistent with chlamydospores. Neither microconidia, macroconidia, nor ascomata were observed. The isolate showed urease, keratinolytic, proteolytic, lipolytic and cellulolytic activity. It grew at 5°C and tolerated up to 6% NaCl; susceptibility to terbinafine was reduced. Phylogenetically, the isolate formed a distinct lineage branching basally to Pseudogeomyces, separated from related taxa by a distance comparable to that between Geomyces and Solomyces.

conclusionsDermkielia gen. nov. (IF 905143) is introduced with Dermkielia cavawata sp. nov. (IF 905164) as the type species. Related ITS sequences in NCBI GenBank suggest that additional species of Dermkielia may be discovered. Dermkielia cavawata is presumably geophilic and possibly linked to forest ecosystems, but it possesses traits that may facilitate opportunistic colonization of human keratinized tissue.
