1 · What the graph read from 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.

2 · The registry

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

Mycobacterium abscessus is the most common cause of rapidly growing mycobacterial chronic lung disease. Recently, two new M. abscessus-related species, M. massiliense and M. bolletii, have been described. Health care-associated outbreaks have recently been investigated by the use of molecular identification and typing tools; however, very little is known about the natural epidemiology and pathogenicity of M. massiliense or M. bolletii outside of outbreak situations. The differentiation of these two species from M. abscessus is difficult and relies on the sequencing of one or more housekeeping genes. We performed extensive molecular identification and typing of 42 clinical isolates of M. abscessus, M. massiliense, and M. bolletii from patients monitored at the NIH between 1999 and 2007. The corresponding clinical data were also examined. Partial sequencing of rpoB, hsp65, and secA led to the unambiguous identification of 26 M. abscessus isolates, 7 M. massiliense isolates, and 2 M. bolletii isolates. The identification results for seven other isolates were ambiguous and warranted further sequencing and an integrated phylogenetic analysis. Strain relatedness was assessed by repetitive-sequence-based PCR (rep-PCR) and pulsed-field gel electrophoresis (PFGE), which showed the characteristic clonal groups for each species. Five isolates with ambiguous species identities as M. abscessus-M. massiliense by rpoB, hsp65, and secA sequencing clustered as a distinct group by rep-PCR and PFGE together with the M. massiliense type strain. Overall, the clinical manifestations of disease caused by each species were similar. In summary, a multilocus sequencing approach (not just rpoB partial sequencing) is required for division of M. abscessus and closely related species. Molecular typing complements sequence-based identification and provides information on prevalent clones with possible relevant clinical aspects.
