Emergence of Trichophyton tonsurans-A Retrospective Multicentre Study of the Dermatophyte Spectrum in Germany.
Article in Mycoses, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundIn mid-2024, German media reported increasing fungal infections by Trichophyton tonsurans linked to visits to barbershops. However, epidemiological data confirming a rise in tinea capitis and tinea corporis due to Trichophyton tonsurans are lacking.
objectivesThis study assesses dermatophyte species and clinical types of infections in German university hospitals in 2018 and 2023. PATIENTS/
methodsThis retrospective, multicentre study analyses mycological culture results from three Departments of Dermatology in Freiburg, Tübingen and Munich. The dermatophyte, along with the sampled body site, age and gender of the affected patient, was recorded.
results1915 patients (male: 66.1%; mean age: 50 ± 24 years) with a dermatophyte-positive culture were identified. The most common dermatophyte was Trichophyton rubrum (2018: 78.7%; 2023: 66.3%) with tinea pedis and tinea unguium being the most prevalent types of infection. An increase in tinea corporis and tinea capitis was observed, with tinea capitis doubling from 4.3% to 9.3%. In 2023, Trichophyton tonsurans emerged as the prevailing dermatophyte (67.6%) in tinea capitis and as the second most frequent agent in tinea corporis (26.3%). This dominance of Trichophyton tonsurans was consistently observed across all three study centres. Trichophyton tonsurans affected patients presented a median age of 18 years in 2023 (vs. 9 years in 2018) and an amplified imbalance towards the male gender.
conclusionsThe pathogen spectrum and infection patterns have changed in Germany due to the increase of Trichophyton tonsurans infections. Intensified screening and hygiene measures, as well as adaptation of initial empiric treatment of tinea capitis, should be considered.
