Kikuchi-Fujimoto disease concurrent with aseptic meningitis or encephalitis in children: a case-control study.
Article in BMC pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 was performed to summarize the clinical and laboratory features of children with Kikuchi-Fujimoto disease concurrent with aseptic meningitis or encephalitis.
methodsA case-control study of children diagnosed with Kikuchi-Fujimoto disease at Beijing Children's Hospital from January 2015 to December 2023 was conducted to determine the characteristics of the disease when concurrent with aseptic meningitis or encephalitis.
resultsOur cohort of 64 cases of Kikuchi-Fujimoto disease included 16 children with central nervous system involvement and 48 controls. Among the 16 affected children, the male: female ratio was 1.7:1.0. The age at onset ranged from 3 to 13 years, with a median age of 8 years. All 16 cases had fever, 15 had cervical lymph node tenderness, 11 had headache, and 14 showed decreased white blood cell counts in routine blood tests. Imaging of the head revealed abnormalities in 11 cases, specifically leukoencephalopathy with mostly bilateral involvement. Cervical lymph node tenderness, headache, confusion, convulsions, and elevated C-reactive protein were significantly associated with Kikuchi-Fujimoto disease concurrent with aseptic meningitis or encephalitis (p < 0.05). There was also a significant difference in lactate dehydrogenase levels between children with and without central nervous system involvement (575.8 ± 221.3 vs. 440.0 ± 163.1 U/L, p = 0.014).
conclusionsFor children with Kikuchi-Fujimoto disease, careful evaluation for central nervous system involvement is warranted when cervical lymph node tenderness, elevated C-reactive protein, or elevated lactate dehydrogenase is present. In children presenting with aseptic meningitis or encephalitis, Kikuchi-Fujimoto disease should be considered as a differential diagnosis. CLINICAL TRIAL NUMBER: Not applicable.
