  1. Data are mean ± SD, median (interquartile) or n (%). SOFA Sequential Organ Failure Assessment, ranging from 0 to 24, with higher scores indicating a greater degree of organ failure, ECI Elixhauser comorbidity index, and we used the modified vanWalraven Elixhauser comorbidity score in our study, which consists of 30 comorbidity diseases, range from -19 to 89 points, with higher scores indicating a greater risk of hospital mortality, MAP mean arterial pressure, HR heart rate, RR respiratory rate, SAPS-I simplified acute physiologic score-I; SAPS-II simplified acute physiologic score-II, ICU intensive care unit, COPD chronic obstructive pulmonary disease. The definitions and diagnositic criteria for sepsis, severe sepsis and septic shock were made according to the Surviving Sepsis Campaign Guidelines [1, 13, 14]. No variable had a missing value
