The purpose of this study is to explore the factors associated with interdialytic blood pressure variability in maintenance hemodialysis patients, especially the association between volume status and blood pressure variability.

interdialytic blood pressure
Ambulatory BP monitoring was performed after the midweek hemodialysis session for 44 hours. Ambulatory BPs were recorded every 20 minutes during the day (6 AM to 10 PM) and every 30 minutes during the night (10 PM to 6 AM) in the nonaccess arm, We use the coefficient of variation or standard deviation in interdialytic blood pressure as a indicator of systolic blood pressure variability.
44 hours
volume status:group1 over volume status,group2 normal volume status,group3 low volume status
night blood pressure：group1 nondipper,group2 dipper,group3 extreme dipper,group4 riser
interdialysis weight gain:group1 \>5% dry weight,group2 \<5% dry weight
