Fig. 4. Associations between peripheral immunity markers and brain structure.
Neutrophil (A), SII (B), platelet (C), NLR (D) are negatively associated with volume of cortical and subcortical structures (Bonferroni-corrected, P < 0.05). Models are adjusted for age at baseline, sex, ethnicity, education, SBP and DBP. T-value represents the correlation coefficient of the linear regression. SBP systolic blood pressure, DBP diastolic blood pressure, NLR neutrophils/lymphocytes ratio, SII systemic immune-inflammation index (neutrophils×platelets/lymphocytes).
