Participant Flow

The study was conducted on stable inpatient HD patients between October 2008 and September 2010. The study design was based on different possible dose levels of APC infusion: 12, 18, 24, 30 μg/kg/h. The initial starting dose of APC for the first patient was 12 μg/kg/h. When a study patient's PTT was \<60 s, the starting dose for the next study patient was increased by 6. There were no patient's in the 30 μg/kg/h group with a PTT of \<60 s

Participants were evaluated for inclusion and exclusion criteria and immediately enrolled in the study.
