Langerhans cell histiocytosis of the jaw: clinical analysis of 68 cases.
Article in Orphanet journal of rare diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThis study aims to investigate the clinical characteristics, imaging features, treatment, and prognostic factors of jaw Langerhans cell histiocytosis (JLCH), providing valuable insights for its clinical diagnosis and management.
methodThis study retrospectively analyzed the clinical and follow-up data of JLCH patients treated between January 2010 and January 2024. Data collected included gender, age, symptoms, imaging findings, treatment strategies, and outcomes. Univariate and multivariate Cox regression analyses were performed using SAS software to identify factors affecting treatment outcomes, with P ≤ 0.05 considered statistically significant.
resultsA total of 68 patients (50 males, 18 females; median age 13.5 years) were included. Forty percent of patients were under 10 years old, and 71% had mandibular involvement. Disease classification included 49 cases of single-system unifocal (SS-s) disease, 10 cases of single-system multifocal (SS-m) disease, and 9 cases of multi-system (MS) disease. Common symptoms included jaw or tooth pain (28 cases), facial swelling (22), gingival ulceration (10), and loose teeth (9). Imaging revealed periodontal disease-like (7), cyst-like (17), and osteomyelitis-like (44) lesions. Univariate and multivariate Cox regression analyses identified that female patients had a lower risk of progression (P = 0.014, HR 0.071), while SS-m (P = 0.019, HR 4.992) and MS patients (P = 0.030, HR 4.182) exhibited higher progression risks compared to SS-s patients. Cyst-like (P = 0.001, HR 0.054) and osteomyelitis-like lesions (P < 0.001, HR 0.023) were associated with lower progression risks compared to alveolar lesions.
conclusionJLCH can affect individuals of all ages, though it is more common in children. Factors such as gender, lesion multiplicity, and lesion type (alveolar) are significant in predicting disease progression. Complete surgical resection combined with radiotherapy offers the highest likelihood of cure for SS-type JLCH.
