Correlation of CSF l-lactate concentrations, QAlb, QIgG, and CSF WCC with the spinal cord lesion load (as measured in vertebral segments) in patients with acute MOG-IgG-positive myelitis. Note that the CSF WCC correlated with the spinal lesion load only after exclusion of outliers with extraordinarily high lesion load (15 or more segments). The most significant correlation was found with CSF l-lactate levels. QAlb, albumin CSF/serum ratio, QIgG, IgG CSF/serum ratio; WCC, white cell count
