Successful Treatment of Refractory Pemphigus Vulgaris with Ultra-Low-Dose Rituximab in a High-Risk Patient: A Case Report.
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
Pemphigus vulgaris is a rare autoimmune blistering disease that causes painful erosions on the skin and mucous membranes. Standard treatments include corticosteroids, immunosuppressants, and rituximab. However, managing pemphigus vulgaris in elderly patients with comorbidities remains challenging. We report a 73‑year‑old male patient who had pemphigus vulgaris poorly controlled by glucocorticoids and a history of malignancy after surgical resection. He was then treated with add-on ultra‑low‑dose rituximab (100 mg) combined with methylprednisolone. The patient achieved complete clinical remission without significant adverse events. The response has been sustained during 6 months of follow‑up. Our case suggests that ultra‑low‑dose rituximab may be a safe and effective option for selected patients with refractory pemphigus vulgaris, particularly those with advanced age or cancer. Longer follow-up and further studies are needed to evaluate its long-term efficacy and safety.
