  • Note:—dNPSLE indicates neuropsychiatric systemic lupus erythematosus with diffuse syndromes.

  • a The statistical analysis between the groups was performed using 1-way analysis of variance controlling for age and sex. FA is a dimensionless measure. Diffusivity is given in square millimeters second−1.

  • b P value for MS vs HCs.

  • c P value for SLE vs HCs.

  • d P value for MS vs SLE.
