First isolation of Mycobacterium brisbanense from humans in the Americas.

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
backgroundMycobacterium brisbanense is a rare nontuberculous mycobacteria and was for the first time detected in the Americas in humans. However, this, like several other species of mycobacteria, may be underreported worldwide. Therefore, their study is increasingly important.
objectivesThe aim of this article is to report and analyse the first seven human isolates of M. brisbanense in the Americas, derived from six Brazilian patients.
methodsWe sequenced the genes hsp65, rpoB and 16s rRNA, of seven mycobacterial clinical isolates, constructed a phylogenetic tree, and determined their drug susceptibility profile.
findingsThe regions sequenced were highly similar between the M. brisbanense type strain and the Brazilian strains. Similarly, their susceptibility profiles were similar to that of M. brisbanense type strain, except for two antibiotics tested, cefoxitin and doxycycline. MAIN
conclusionsAll studied strains were identified at the species level by a concatenated tree as M. brisbanense.
