Figure 6.
Temporal progression of clinical features and investigations. (A) The times of first appearance of the main clinical features for each patient, up to 120 days after onset of neurological symptoms. (B) The times of all CSF pleocytosis or oligoclonal bands, and all abnormal EEG or MRI findings. Median and interquartile ranges are shown. P-values in B represent Mann–Whitney U-tests for each blue-red pairing. OCB = CSF-specific oligoclonal bands. Percentages (bracketed) show the frequency of each feature or investigation within the total NMDAR-antibody patient cohort.
