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

Blastomyces dermatitidis and Histoplasma capsulatum are dimorphic fungi that often cause self-limited respiratory infections. However, they may also cause severe disseminated disease, depending on the level of the exposure to the organism and the host immune status. In addition, patients with infections caused by these fungi may have very similar clinical presentations. Although microbiologic culture is a standard method for detecting these pathogens, their recovery may require days to weeks, and the manipulation of cultures presents a significant safety hazard to laboratory personnel. Therefore, the goal of this study was to design a rapid, real-time PCR assay to detect and differentiate B. dermatitidis and H. capsulatum from culture isolates and directly from clinical specimens. Primers and fluorescence resonance energy transfer hybridization probes were designed to target the histidine kinase and glyceraldehyde-3-phosphate dehydrogenase genes of B. dermatitidis and H. capsulatum, respectively. The analytical sensitivity of the assay was determined to be 100 copies/μl for both fungi. From culture isolates, the assay demonstrated 100% specificity and 100% sensitivity for B. dermatitidis and 100% specificity and 94% sensitivity for H. capsulatum. Detection directly from 797 clinical specimens demonstrated specificities and sensitivities of 99% and 86% for B. dermatitidis and 100% and 73% for H. capsulatum compared with the results for culture. This real-time PCR assay provides a rapid method for the detection of B. dermatitidis and H. capsulatum from culture isolates and directly from clinical specimens.
