Actinomycetes isolates of arid zone of Indian Thar Desert and efficacy of their bioactive compounds against human pathogenic bacteria.
Article in Biologia futura, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Twenty-six morphotypes of actinomycetes bacteria were isolated from the soils of arid zone of Indian Thar desert, Rajasthan. A significant and positive correlation was found between density of actinomycetes isolates and availability of nitrogen in sandy soil of arid zone suggesting the influence of soil nitrogen on occurrence and propagation of actinomycetes in this region. Molecular identification based on 16S rRNA gene sequencing revealed that the bacterial isolates belong to four actinomycetes genera, viz. Streptomyces (22 species), Nocardiopsis (two species), Saccharomonospora (one species) and Actinoalloteichus (one species). The preliminary screening of 26 isolates against five human pathogenic bacteria, viz. Escherichia coli, Vibrio cholera, Salmonella enterica typhimurium, Staphylococcus aureus and Enterococcus faecalis, showed that only four isolates, viz. Streptomyces sp. (ITD-27), S. enissocaesilis (ITD-29), S. Malachitospinus (ITD-35) and Streptomyces sp. (ITD-47), had antibacterial activity. The secondary screening of these four isolates revealed that the isolate S. malachitospinus (ITD-35) showed the maximum growth inhibition zone and inhibited the growth of all tested gram-positive and gram-negative pathogenic bacteria. Gas chromatography-mass spectrometry analysis of S. malachitospinus (ITD-35) cultural filtrate in n-butanol solvent identified three antibacterial compounds of medicinal significance, viz. 3-octanone, neopentyl isothiocyanate and 2-methyl butyl isothiocyanate.
