Figure 1.
Comparison of serum IL-6 levels between healthy controls and HS patients with different degrees of disease severity. Serum IL-6 levels in a group of Hurley stage I, II, and III patients were 33.4 ±8.9 pg/ml (range: 22.3–52.8 pg/ml), 145.6 ±33.6 pg/ml (range: 94.6–198.0 pg/ml), and 191.4 ±48.1 pg/ml (range: 106.4–301.1 pg/ml), respectively. Compared to IL-6 levels in the healthy control group (34.9 ±11.4 pg/ml, range: 18.8–55.5 pg/ml), the serum IL-6 levels in Hurley stage II and III patients were significantly increased, and the difference was statistically significant (p-values of both < 0.001)
