Recognizing Pemphigus Vulgaris in a Low Prevalence Setting: A Journey Through Multiple Diagnoses.

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
Pemphigus vulgaris (PV) is an autoimmune blistering disease that may present predominantly with mucosal involvement and is frequently misdiagnosed as infectious or inflammatory conditions. We describe a 72-year-old Filipino woman with a 3-month history of painful oral and genital ulcerations and subsequent flaccid bullae who was initially diagnosed and treated sequentially for candidiasis, disseminated herpes zoster infection, and Behçet's disease based on International Criteria for Behçet's Disease scoring. Despite multiple antimicrobial therapies, her symptoms progressed. Definitive evaluation revealed intraepidermal acantholysis on histopathology and intercellular IgG and C3 deposition in a characteristic "fishnet" pattern on direct immunofluorescence, with positive desmoglein 1 and 3 antibodies, confirming PV. Prompt initiation of systemic corticosteroids led to rapid clinical improvement. This case underscores how diagnostic anchoring and reliance on classification criteria can delay recognition of autoimmune blistering disease, highlighting the need for early biopsy and direct immunofluorescence in persistent mucocutaneous ulceration.
