A case of toxic epidermal necrolysis in an elderly female patient.
Article in SAGE open medical case reports, 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
Toxic epidermal necrolysis is a rare, potentially fatal, and mainly drug-induced dermatological emergency that requires immediate medical intervention. It is characterized by extensive erythema, widespread sloughing of the epidermis and mucous membranes, and tissue necrosis. The condition can result in significant skin loss and serious complications such as sepsis and shock. With a mortality rate of 30%-50%, early recognition and prompt treatment are critical to improving outcomes. Here we report the case of an 85-year-old woman who presented to our emergency department with confluent erythematous maculopapular eruptions affecting more than 60% of her body surface area, accompanied by a positive Nikolsky sign and widespread areas of denuded skin, including involvement of the oral, vaginal, and anal mucosa following self-administered trimethoprim-sulfamethoxazole for a urinary tract infection. A skin biopsy revealed transepidermal necrosis with minimal active inflammation in the upper dermis. We initiated systemic glucocorticoid therapy along with fluid resuscitation. The patient remained stable throughout hospitalization. By the time of discharge, dermatological findings had significantly improved, and the skin was in the re-epithelialization phase. In conclusion, a high index of clinical suspicion for toxic epidermal necrolysis is necessary when a patient receiving trimethoprim-sulfamethoxazole presents with blistering and/or skin sloughing. Prompt treatment with immunosuppressive agents and supportive care is essential to improve outcomes.
