Langerhans cell histiocytosis in sphenoid sinus with vision impairment: Case report and literature review.
Review in Science progress. 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 (LCH) is a neoplastic disease characterized by aberrant proliferation of the mononuclear phagocyte system, predominantly affecting children under the age of 3 years. Although LCH can affect almost all organs, sinus involvement is rare. This case report documents a 9-year-old boy presented with vision impairment and intermittent headache on the right side. The CT scan and MRI examination revealed the presence of a soft mass in the right atrium of sphenoid sinus, which impacted the right optic canal. Biopsy results confirmed the presence of LCH. Considering the involvement of optic canal and vision impairment, meticulous debridement was performed followed by a 12-month standard chemotherapy. After 2 years of follow-up, the patient showed significant improvement, despite the presence of an encapsulated cyst in the right sphenoid sinus. This case highlights the importance of considering LCH when encountering an isolated soft mass accompanied by decreased vision in the sphenoid sinus. A thorough physical examination, laboratory tests, and imaging methods should be performed, with a biopsy being necessary to confirm the type of lesion and guide the appropriate treatment.
