The univariate Cox hazard regression analysis indicated that there was no significant association between the development of a decreased blood flow rate from the vascular access catheter and catheter position, age, gender, height, SOFA score, sepsis or severe infectious diseases, heart failure, mode of CRRT (CVVHDF), serum albumin level, hemoglobin level, or activated coagulation time (Table 3). Here, ALB is linked to heart failure.
