IL4 and Stroke: In contrast, lower concentrations of HDL, CD3, IL-4, IL-6, IL-10, TNF-α, and INF-γ were negatively correlated with hyperlipidemia comorbidity in stroke patients (HDL: P = 0.048, χ2 = 4.716; CD3: P = 0.003, χ2 = 9.114; IL-4: P = 0.001, χ2 = 10.633; IL-6: P = 0.001, χ2 = 9.881; IL-10: P = 0.020, χ2 = 6.173; TNF-α: P = 0.001, χ2 = 10.875; INF-γ: P = 0.001, χ2 = 10.717) (Fig. 2C).
