MMP-7 and total protein CSF concentrations were positively correlated in the overall samples (Spearman; r = 0.5303 and p = 0.0001) and in MS and OIND patients (Spearman; r = 0.4424 and p = 0.0112, r = 0.8821 and p < 0.0001, respectively) (Figure 1H). The gene discussed is MMP7; the disease is myeloid sarcoma.
