This study examines patients based on the Systemic Inflammatory Response Syndrome (SIRS) criteria, focusing on body temperature, heart rate, respiratory rate, and white blood cell count. Patients are classified as SIRS or non-SIRS based on meeting 2 or fewer criteria. SIRS patients are further categorized into SIRS-2, SIRS-3, and SIRS-4 subgroups according to the number of positive criteria met.

Patients Assessed with The SIRS Criteria Patients who met more than 2 items of the SIRS criteria were defined as SIRS patients while patients who met 0 or 1 item of the SIRS criteria were defined as non-SIRS patients. In this study, SIRS patients were further classified into 3 sub-groups. SIRS-2, 3 and 4 indicate patients who had 2, 3, and 4 items positive in the SIRS criteria, respectively.
