Nail Involvement in Pemphigus: A Clinical and Dermoscopic Prospective Study.
Article in Skin appendage disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Nail involvement in pemphigus (NIP) was considered as a rare finding and a predictor factor of the severity of pemphigus. The diagnosis of NIP can be challenging, as it can be mistaken for other nail disorders. The aim of our study was to provide an overview of NIP, with a focus on the dermoscopy role to detect these nail changes. Methods: A monocentric prospective study was performed from January 2018 to December 2022, investigating clinically and with a dermoscope NIP. Results: Our study included 32 patients, among them 6 patients with NIP. The mean age was 53 years. The average duration of the disease at presentation was 4.5 months. Five patients (83%) had pemphigus vulgaris and 1 patient was diagnosed with paraneoplastic pemphigus. In 5 cases (83%), the disease was severe, with 4 cases having frequent exacerbations (66.7%). The average number of nails involved was 9. In 3 cases, only the fingernails were involved. The nail lesions were concomitant to the mucocutaneous lesions in half our cases. Onycholysis and subungual hemorrhage were the most frequent dermoscopic findings (83%). Paronychia and dyschromia were seen in 4 patients. In 3 cases, cuticular loss and onychomadesis were seen. Conclusion: Dermoscopic features such as subungual hemorrhage, onycholysis, and paronychia can help distinguish pemphigus-related nail changes from other conditions.
