Association of the systemic immune-inflammatory index and systemic inflammatory response index with all-cause and cardiovascular mortality in individuals with metabolic inflammatory syndrome

High levels of SII and SIRI were independently associated with increased risks of all-cause and cardiovascular mortality, with SIRI showing superior predictive performance. This study underscores the prognostic utility of SII and SIRI in patients with MIS and provides valuable insights into their roles in mortality risk assessment.
