[Tinea corporis due to the rare geophilic dermatophyte Microsporum praecox].
Article in Der Hautarzt; Zeitschrift fur Dermatologie, Venerologie, und verwandte Gebiete, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
A 10-year-old girl suffered from tinea corporis with erythematosquamous and centrifugal growing, sparse itching lesions of her right lower arm. Fluorescence optical Blankophor® preparation from skin scrapings revealed fungal hyphae. On Sabouraud's dextrose agar, the fast growing dermatophyte formed flat, peripheral radiating and convolved colonies with white, slightly yellowish to beige brown stained granular and powdery surface. The reverse side of the colonies was smooth with luminous yellow colour. Microscopically, an attitude of thin-walled spindle-shaped and echinulate (with small spins) and lanceolate macroconidia appeared. The small based macroconidia are raised in the middle and end part, however, pointy at the end ("spearhead"). Three to six or seven across septae are formed. The small piriform microconidia had an orthotropic arrangement. Chlamydospores were also formed. Urease activity was positive. Macromorphologically, Trichophyton (T.) interdigitale (formerly T. mentagrophytes) was suspected. Due to the shape of macroconidia, Microsporum (M.) gypseum and M. fulvum were also considered as possible species identification. Direct uniplex-PCR-EIA of the strains revealed negative results for T. rubrum, T. interdigitale, T. anamorph of Arthroderma benhamiae and M. canis. Sequencing analysis of the ribosomal ITS-region (18 S rRNA, ITS1, 5.8 S rRNA, ITS2, 28 S rRNA) and of the translation elongation factor 1‑alpha (tef-1-alpha) gene revealed the dermatophyte species M. praecox. Topical treatment was done using ciclopiroxolamine cream. M. praecox represents a geophilic dermatophyte, morphologically resembling M. gypseum. Horses are often the source of infection. In humans, M. praecox causes tinea corporis and tinea capitis. For oral treatment of dermatomycosis due to M. praecox, griseofulvin and terbinafine can be used.
