Correlation analyses of CSF-CXCL13 and different routine CSF findings in the four groups.
| Parameter | NIND | NID | AIND | NPL |
|---|---|---|---|---|
| n | 208 | 273 | 147 | 49 |
| Leucocyte count (/µL) | r = 0.045 | r = 0.132 | r = 0.560 | r = 0.655 |
| Lymphocyte count (/µL) | r = 0.158 | r = 0.139 | r = 0.495 | r = 0.748 |
| Monocyte count (/µL) | r = 0.120 | r = 0.066 | r = 0.163 | r = 0.358 |
| Plasma cell count (/µL) | - | r = 0.271 | r = 0.311 | - |
| QAlb (CSF/S) | r = 0.135 | r = 0.347 | r = 0.336 | r = 0.674 |
Correlation analyses between CSF-CXCL13 and the routine CSF parameters were performed using Spearman’s rank coefficient (r). Correlation analyses of plasma cells in NIND and NPL could not be performed due to the low number of detected cells with differential cytology. All r-values are rounded. QAlb: CSF-albumin/serum-albumin (albumin ratio), CSF: cerebrospinal fluid, AIND: autoimmune inflammatory neurological diseases, NPL: CNS-neoplasia, NIND: non-inflammatory neurological diseases, NID: neuroinfectious diseases.
