Molecular epidemiology and antifungal susceptibilities of Aspergillus species isolated from patients with invasive aspergillosis.
Article in Revista da Associacao Medica Brasileira (1992), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
objectiveThe aim of this study was to evaluate the demographic data, molecular epidemiology, and in vitro antifungal susceptibility results of patients with Aspergillus isolated from various clinical specimens.
methodsA total of 44 Aspergillus strains were studied. The definition of invasive aspergillosis in patients was made according to European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) criteria. Strains were phenotypically and molecularly identified. Demographic characteristics of patients and genotypes of strains were evaluated. Phylogenetic analysis was done by the The Unweighted Pair-Group Method with Arithmetic Mean (UPGMA). Antifungal susceptibility of strains was determined according to The Clinical and Laboratory Standards Institute (CLSI)-M61-Ed2 and The European Committee on Antimicrobial Susceptibility Testing (EUCAST).
resultsA total of 11 patients were classified as proven and 33 as probable invasive aspergillosis. There was a statistically significant difference in age groups, subdisease, neutropenic, and receiving chemotherapy between groups. A total of 23 strains were identified as Aspergillus fumigatus, 12 as Aspergillus niger, 6 as Aspergillus flavus, and 3 as Aspergillus terreus. Phylogenetic analysis revealed five different genotypes. No statistical difference was found in the comparisons between patients groups and genotype groups. There was a statistically significant difference between genotype groups and voriconazole, posaconazole, and itraconazole Minimum Inhibition Concentration (MIC).
conclusionAccurate identification of strains and antifungal susceptibility studies should be performed due to azole and amphotericin B resistance. Genotyping studies are important in infection control due to identifying sources of infection and transmission routes.
