Meta-analysis of serum IFN-γ, IL-4, IL-17, IL-23, IL-6, TNF-α, and IL-10 levels in patients with psoriasis vulgaris of blood-heat syndrome. The mean difference (MD) in IFN-γ, IL-4, IL-17, IL-23, IL-6, TNF-α, and IL-10 levels of patients with psoriasis compared with controls. The point estimate (center of each green square) and statistical size (proportional area of the square) are represented. Horizontal lines indicate 95% confidence intervals. The subtotal and total MDs (diamonds) were calculated using random-effects models.
