A Single-Center Profile of Pemphigus in China: Significant Diagnostic Delay and Evolving Treatment Patterns.
Article in Clinical, cosmetic and investigational dermatology, 2026. 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
Purpose: Pemphigus encompasses a group of rare and potentially life-threatening autoimmune bullous diseases. Epidemiological research on pemphigus in China remains limited. This study aimed to analyze the clinical characteristics, diagnostic delay, and initial treatment patterns of patients with newly diagnosed pemphigus at a tertiary center in China. Patients and Methods: This retrospective study included patients newly diagnosed with pemphigus between January 2020 and December 2024 at the outpatient department of Peking Union Medical College Hospital. Demographic and clinical data were collected and analyzed. Results: A total of 138 patients were included. Pemphigus vulgaris was the most prevalent subtype (68 cases, 49.3%), followed by pemphigus erythematosus (34 cases, 24.6%), pemphigus foliaceus (13 cases, 9.4%), and pemphigus herpetiformis (11 cases, 8.0%). Notably, the diagnostic delay was substantial, with a median of 5.0 (2.0-12.0) months, and 106 patients (76.8%) had been misdiagnosed before a definitive diagnosis was made. Regarding initial treatment, the most frequently used drugs were corticosteroids (104/132, 78.8%), followed by mycophenolate mofetil (33/132, 25.0%), Tripterygium wilfordii Hook F (29/132, 22.0%), minocycline (28/132, 21.2%), and rituximab (24/132, 18.2%). There was no significant difference among the subtypes in the proportion of patients receiving non-steroidal therapies. Conclusion: These findings highlight a significant diagnostic delay and outline evolving treatment patterns for pemphigus in a contemporary Chinese cohort. This information may inform future research directions and health policy decisions for managing this rare disease.
