Association between RAR and in-hospital mortality of patients with sepsis and atrial fibrillation. RAR was entered as a continuous variable. Hazard ratios 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. The black and blue lines represent the estimated values and their corresponding 95% confidence intervals, respectively
