Frequency of the Mating-Type (MAT1) in Histoplasma capsulatum Isolates from Buenos Aires, Argentina.
Article in Mycopathologia, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Sex is genetically determined in Histoplasma capsulatum, governed by a sex-specific region in the genome called the mating-type locus (MAT1). We investigate the distribution of isolates of two H. capsulatum mating types in the clades circulating in Buenos Aires, Argentina. Forty-nine H. capsulatum isolates were obtained from the culture collection of the Mycology Center. The MAT1 locus was identified by PCR from the yeast suspension. The analysis of forty-eight isolates from clinical samples exhibited a ratio of 1.7 (MAT1-1:MAT1-2) and the only isolate from soil was MAT1-1. Forty-five H. capsulatum isolates belonged to the LAm B clade (H. capsulatum from Latin American group B clade) and showed a ratio of 1.8 (MAT1-1:MAT1-2). These results suggest an association between the mating types in isolates belonging to the LAm B clade. It remains to be defined whether a greater virulence should be attributed to the differences between the strains of the opposite mating type of the LAm B clade.
