Graden af nyreinsufficiens blev defineret i henhold til baseline kreatininclearance (normal nyrefunktion ved kreatininclearance > 80 ml/ min; mild insufficiens ved kreatininclearance = 50- 79 ml/ min; moderat insufficiens ved kreatininclearance = 30- 49 ml/ min og svær insufficiens ved kreatininclearance = 10- 29 ml/ min).
The degree of renal impairment was defined according to baseline creatinine clearance (normal renal function when creatinine clearance > 80 ml/ min; mild impairment with creatinine clearance=50 to 79 ml/ min; moderate impairment with creatinine clearance=30 to 49 ml/ min and severe impairment with creatinine clearance=10 to 29 ml/ min).
