Adult multisystem Langerhans cell histiocytosis with cutaneous involvement manifesting as extensive flexural erosions.
Article in BMJ case reports, 2023. 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
Langerhans cell histiocytosis is a great imitator of other diseases with an often-delayed diagnosis leading to a concerning delay in commencing treatment. We present the case of a male who was previously diagnosed with Hailey-Hailey disease, in whom several treatment options had failed, was referred to the dermatology team for evaluation of a 3-month atypical, extensive, painful and pruritic cutaneous flexural eruption. On systems review, he reported a 2-year history of polyuria and polydipsia. Repeat skin biopsy revealed a prominent histiocytic infiltrate on histopathology with corresponding positive expression of Langerin (CD207), S100, CyclinD1 and p-ERK on immunohistochemistry staining. An MRI of the brain demonstrated posterior pituitary enhancement. The clinical presentation, biopsy and investigations confirmed a diagnosis of a multisystem Langerhans cell histiocytosis, which resulted in longstanding patient morbidity. With considerable multidisciplinary teamwork, a gradual and sustained resolution of his lesions, pain, polyuria and polydipsia was achieved.
