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 [M. abscessus (sensu lato) or M. abscessus complex] comprises three closely related species: M. abscessus (sensu stricto), hereafter referred to as M. abscessus, M. bolletii and M. massiliense. We describe here an accurate and robust method for distinguishing M. chelonae from M. abscessus, M. bolletii and M. massiliense, using polymerase chain reaction (PCR) and the sequencing of house-keeping gene targets (hsp65 and rpoB). Sequencing of the sodA gene is of little additional value in discriminating between species, but M. massiliense can be rapidly identified by amplification of the truncated erm(41) gene without the need for amplicon sequencing. We have applied the method to 81 isolates from 40 patients from two hospitals, the majority of whom were cystic fibrosis (CF) patients. Of these patients, 21 had previously been identified as M. chelonae and 59 as M. abscessus complex using commercial line probe assays. We identified these as 46 M. abscessus isolates, 20 M. massiliense isolates, five M. bolletii isolates and nine M. chelonae isolates and confirmed the one M. fortuitum isolate. This is the first study that has identified the individual members of the M. abscessus complex in a UK cohort of mainly CF patients.
