Subgroup analyses of RAR in patients with sepsis and atrial fibrillation. Hazard ratios (HRs) were adjusted for age, sex, MI, CHF, cerebrovascular disease, chronic pulmonary disease, rheumatic disease, diabetes, renal disease, liver disease, MV, RRT, serum hematocrit, MBP, temperature, SPO2, potassium, INR, PT, and SOFA score. RAR, red blood cell distribution width-to-albumin ratio; MI, myocardial infarction; CHF, congestive heart failure; MV, mechanical ventilation; RRT, renal replacement therapy; MBP, mean blood pressure; SPO2, percutaneous oxygen saturation; INR, international normalized ratio; PT, plasma prothrombin time; SOFA, Sequential Organ Failure Assessment
