Fig. 4From: Coenzyme Q10 dose-escalation study in hemodialysis patients: safety, tolerability, and effect on oxidative stressEffect of hemodialysis (HD) on plasma concentrations of CoQ10 in study subjects administered 1800 mg of CoQ10 for 14 days (n = 10). Dark bars indicate total CoQ10 levels prior to standard hemodialysis treatment, lighter bars are following hemodialysis. Error bars indicate SD of the means (paired T-test for means p = 0.72)Back to article page
