In terms of cyst size and cyst volume, IL6 expression was positively correlated with cyst size (r = 0.22, P = 0.013) and cyst volume (r = 0.25, P = 0.005), and IL10 expression was also positively correlated with the cyst size (r = 0.24, P = 0.006) and cyst volume (r = 0.26, P = 0.002). The gene discussed is IL6; the disease is cyst.
