Cox's model with time-dependent covariates showing the estimated hazard ratios (HRs) for 30-day mortality in the postsurgical acute dialysis patients§.

NOTE. Data are number (%) of patients, unless otherwise indicated.Abbreviations: APACHE, acute physiology and chronic health evaluation; BUN, blood urea nitrogen; CVVH, continuous venovenous hemofiltration; IABP, intraaortic balloon pump; MBP, mean blood pressure; IHD, intermittent hemodialysis; TPN, total parenteral nutrition; SLED, sustained low-efficiency dialysis.§Adjusted for gender, age, body mass index, elective operation, cardiopulmonary resuscitation, extracorporeal membrane oxygenation, cardiopulmonary resuscitation, ventilator use, days from hospital admission to dialysis, NPO status, total parenteral nutrition, time-varying variables (blood pressure, BUN, creatinine, lactate, urine output, body weight, time-varying three day accumulative diuretic dose, daily dialysis modality and dialysis intensity), anuria, inotropic equivalent, lactate, sodium, potassium, APACHE II at initial dialysis, diabetes mellitus, hypertension, congestive heart failure, cirrhosis, chronic kidney disease, sepsis, shock, systemic organ failure (central nervous system, respiratory, cardiac, liver), operation categories (abdominal, cardiovascular, chest, neurology, urology, orthopedic), and indication for dialysis (azotemia, fluid overload, hyperkalemia, oliguria, acidosis).∥Inotropic equivalent = [(dopamine+dobutamine)+(milrinone×15)+[(epinephrine+norepinephrine+isoproterenol)×100] in mcg/kg/min [35], [40].
