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

Triazole resistance in Aspergillus fumigatus is an uncommon but rising phenomenon. Susceptibility testing is rarely performed and can take 48 h or longer, which is an impediment to effective therapy. Molecular diagnostic probing of well-defined resistance mechanisms, which serve as surrogate markers, provides an alternative approach to rapidly (within hours) and efficiently identify resistant strains. The mechanisms of triazole resistance in A. fumigatus are limited to amino acid substitutions in the drug target Cyp51A and include amino acid substitutions at the positions Gly 54, Gly 138, Met 220, and Leu 98, coupled with a tandem repetition in the gene promoter. We report the development of a real-time PCR assay utilizing molecular beacons to assess triazole resistance markers in A. fumigatus. When combined in a multiplex platform, the assay provides a comprehensive evaluation of drug resistance in A. fumigatus.
