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

purposeDermatomycoses represent the most frequent form of human fungal infection globally. The conventional diagnostic approach to identify dermatomycoses is based on direct microscopic examination (DME) and fungal culture. However, these procedures suffer from a number of significant limitations. We aim to evaluate the clinical performance of the novel DermatoPlex qPCR assay (SpeeDx) in comparison to conventional methods for the detection of dermatophyte fungi and Candida spp. in skin and nail material.

methodsBetween February and July 2024, 1320 samples from 1252 patients were collected for the investigation of dermatophyte fungi at the Navarra University Hospital in Spain. DME, culture and DNA extraction were systematically executed in all specimens, and the qPCR assay was retrospectively tested. The Novaplex™ Dermatophyte qPCR assay (Seegene) was used in case of discrepancies.

resultsThe DermatoPlex qPCR assay performed well for the molecular detection of dermatophyte fungi and Candida spp. in skin and nail material; with an overall agreement of 75.4% when compared with culture. Among discrepancies, the majority (75.6%) were ultimately confirmed as true-positives, while only 12.4% resulted in false-negative results. Overall, sensitivity of the qPCR method for the diagnosis of dermatomycoses was 2.3x and 1.7x greater (1.7x and 1.6x for dermatophytosis) when compared with DME and culture, respectively.

conclusionThis is the largest clinical evaluation of a qPCR method for the diagnosis of dermatomycoses. Considering the greater sensitivity of molecular techniques over conventional procedures, the DermatoPlex assay emerges as a reliable and promising qPCR method for the diagnosis of cutaneous mycoses.
