Comparison of the activities of the classical (CP), lectin (LP) and alternative pathways (AP) in hemodialysis (HD) patients and healthy controls. White column indicates HD patients, and black column indicates healthy controls. (a) The HD patients enrolled in the present study had significantly higher activity levels of all three complement pathways than the 204 healthy controls. (b) After group matching for age, 64 HD patients also had significantly higher activity levels of all three complement pathways compared with the 56 healthy controls. *P < 0.01; data are shown as the mean ± SD.
