Change in measured BV between 1st and 2nd BVA (in %) according to change in measured post dialysis weight (in kg). Change in measured BV(blood volume) (y-axis) is the difference between measured BV at the second BVA (blood volume analysis measurement) and the BV measured at the first BVA. The change in post-HD (post-hemodialysis) (y-axis) weight equals the post-HD weight on the day of the second BVA minus the post-HD weight on the day of the first BVA. Both the change in measured BV and the change in post-HD weights were calculated for every patient. Linear regression was performed and shows no linear relationship between changes in post-HD weight and changes in measured BV (coefficient of determination, r 2 = 0.08)
