Successful treatment of refractory pyoderma gangrenosum with risankizumab in a 57-year-old patient: A case report.

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
Pyoderma gangrenosum is a neutrophilic dermatosis characterized by rapidly progressing inflammatory skin lesions. It is often associated with underlying systemic conditions, such as inflammatory bowel disease and rheumatoid arthritis. Patients typically present with erythematous papules and pustules that rapidly evolve into painful ulcers, most commonly affecting the lower extremities. In this case report, we describe a 57-year-old female patient with multirefractory pyoderma gangrenosum localized to the lower left leg. The diagnosis was confirmed based on clinical and histopathological features, with a skin biopsy showing compatible findings. Initial treatments, including topical therapies (high-potency steroids, dapsone, and calcineurin inhibitors) and conventional systemic immunosuppressive therapies (corticosteroids and tumor necrosis factor inhibitors), failed to produce significant improvement. However, treatment with risankizumab, an interleukin-23 inhibitor, resulted in substantial ulcer healing over a few weeks and ultimately led to complete resolution.
