Inhibitory effects of cysteine and cysteine derivatives on germination of sporangiospores and hyphal growth of different Zygomycetes.
Article in Mycopathologia, 2009. 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 in vitro antifungal activity of cysteine (D- and L-cysteine) and its four derivatives (L-cysteine-methyl-ester, N-acetyl-cysteine, N-isobutyryl-D-cysteine, and N-isobutyryl-L-cysteine) were investigated on 20 fungal isolates representing 16 genera (Absidia, Actinomucor, Backusella, Gilbertella, Micromucor, Mortierella, Mucor, Mycotypha, Phycomyces, Rhizomucor, Rhizopus, Saksenaea, Syncephalastrum, Thamnostylum, Umbellopsis, and Zygorynchus). The inhibitory potential of different concentrations of these compounds, ranging from 0.625 to 10 mM, were investigated on the germination of sporangiospores as well as on hyphal extension, using broth microdilution method and agar plate test. Treatment with cysteine and its derivatives resulted in a strong inhibition in most studied strains. At 10 mM of compounds, complete blockage of growth was observed for some isolates. Sensitive species exhibited severe changes in colony morphology in the presence of 10 mM L-cysteine, N-acetyl-cysteine, and N-isobutyryl-L-cysteine. Microscopic observations revealed that 10 mM N-acetyl-cysteine induced dramatic modifications in the structural organization of the hyphae. Results suggest that cysteine and its derivatives have a therapeutic potential against fungal infections caused by Zygomycetes species.
