For reference, the Tukey’s post hoc test following ANCOVA between MS and AQP4-IgG-positive NMOSD groups in NLR showed statistical significance, with estimated least square means (95% CI) of 2.363 (2.084–2.642) for MS and 3.236 (2.593–3.879) for AQP4-IgG-positive NMOSD (p = 0.0415). This evidence concerns the gene AQP4 and myeloid sarcoma.
