Elevated serum neurofilament light chain levels in patients with neuropsychiatric systemic lupus erythematosus: a cross-sectional study.
Article in Lupus science & medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundThe neurofilament light chain (NfL) in cerebrospinal fluid (CSF) and serum as a marker of neuronal damage may be a potential biomarker of neuropsychiatric involvement in SLE (NPSLE).
methods80 patients with SLE were included.We obtained paired serum and CSF samples from 48 patients (NPSLE n=32, non-NPSLE n=16) and 31 controls. The serum and CSF levels of NfL were determined using ELISA.
resultsPatients with NPSLE demonstrated significantly higher levels of serum NfL compared with the non-NPSLE group (mean 31.68±36.63 pg/mL vs mean 16.75±12.48 pg/mL, respectively, p<0.05) and with controls (mean 10.74±4.36 pg/mL, p<0.01). Notably, CSF NfL concentrations in patients with NPSLE showed an upward trend (mean 1600±2852 pg/mL) in contrast to non-NPSLE patients (mean 393.4±191.9 pg/mL) and controls (mean 509.7±358.5 pg/mL). Furthermore, a positive correlation was observed between serum and CSF NfL levels in patients with NPSLE (R=0.8686, p<0.01). Elevated serum triacylglycerol concentrations, C reactive protein and organ damage were linked to increased serum (p=0.002; p<0.001; p=0.036) and CSF (p=0.008; p=0.007; p<0.001) NfL concentrations. In addition, we established a significant correlation between intrathecal NfL concentrations and interleukin-6 levels in the CSF of patients with NPSLE (R=0.5118, p<0.05).
conclusionThe serum NfL levels may be a readily available marker of neuropsychiatric involvement in SLE.
