Dermoscopic Perspective of Pityriasis Versicolor in a Cross-Sectional Study.

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
Background: Pityriasis versicolor is a common superficial fungal infection which is usually easily diagnosed with Wood's lamp examination and 10% potassium hydroxide mount. However, these modalities have varying sensitivity and specificity. Aims and Objectives: This study aimed to ascertain the dermoscopic features of pityriasis versicolor lesionally as well as perilesionally using dermoscopy, a non-invasive diagnostic tool. Materials and Methods: In this cross-sectional study, consecutive patients with pityriasis versicolor underwent dermoscopic examination of lesions and 2 cm around lesions, noting lesional and perilesional features. Semi-objective grading of pigmentation, scaling, and vascularity was done. The association between parameters was determined using heat maps and violin plots with Kolmogorov-Smirnov test. Lesional analysis was performed since lesions at different sides showed disparate features. Results: A total of 353 lesions from 233 patients (males = 150/233; 64.38% and females = 84/234; 36.05%) were studied. On lesional dermoscopy, pigmentary and scaling abnormalities were universal. 258/353 (73.1%) of lesions showed vascular abnormalities. Perilesionally, scaling (223/353; 63.17%) followed by pigmentation (205/353; 58.07%) and vascular changes (111/353; 31.44%) constituted the most common dermoscopic abnormalities and were noted in 294/353 (83.29%) of lesions overall. Increased disease duration corresponded with increased intensity of perilesional pigmentation alterations, perifollicular ( Conclusion: Awareness of dermoscopic features could improve the diagnostic accuracy in doubtful cases of pityriasis versicolor. Vascular findings are common and may point to an underlying inflammatory pathogenesis. Perilesional findings constitute early dermoscopic features of pityriasis versicolor and hint at the need for treatment beyond the confines of lesions. Larger follow-up studies and research into immunopathogenesis may be of further benefit.
