Fig. 1From: Clinical utility of cerebrospinal fluid vitamin D-binding protein as a novel biomarker for the diagnosis of viral and bacterial CNS infectionsComparison of median CSF VDBP levels and interquartile ranges (a) The difference in CSF VDBP levels between the CNS infection (3.20 μg/mL, 1.70–5.10) and non-CNS infection groups (1.10 μg/mL, 0.80–1.80)(P < 0.001). (b) The difference in CSF VDBP levels between the pathogen-identified group (2.34 μg/mL, 1.46–4.53) and non-identified group (3.76 μg/mL, 2.25–5.21)(P = 0.075) within the CNS infection group. Outliers of 1.5 to 3 IQR are marked with circles, and outliers > 3 IQR are marked with squares.
