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

Nonmutational resistance to linezolid is due to the presence of cfr, which encodes a methyltransferase responsible for methylation of A2503 in the 23S rRNA. The cfr gene was first described in animal isolates of staphylococci, and more recently, it has been identified in Staphylococcus aureus from human clinical infections, including in an outbreak of methicillin-resistant S. aureus. In enterococci, cfr has been described in an animal isolate of Enterococcus faecalis from China. Here, we report an isolate of linezolid-resistant E. faecalis (603-50427X) recovered from a patient in Thailand who received prolonged therapy with the antibiotic for the treatment of atypical mycobacterial disease. The isolate lacked mutations in the genes coding for 23S rRNA and L3 and L4 ribosomal proteins and belonged to the multilocus sequence type (MLST) 16 (ST16), which is commonly found in enterococcal isolates from animal sources. Resistance to linezolid was associated with the presence of cfr on an ~97-kb transferable plasmid. The cfr gene environment exhibited DNA sequences similar to those of other cfr-carrying plasmids previously identified in staphylococci (nucleotide identity, 99 to 100%). The cfr-carrying plasmid was transferable by conjugation to a laboratory strain of E. faecalis (OG1RF) but not to Enterococcus faecium or S. aureus. The cfr gene was flanked by IS256-like sequences both upstream and downstream. This is the first characterization of the potential horizontal transferability of the cfr gene from a human linezolid-resistant isolate of E. faecalis.
