    Lactate and the lactate-to-albumin ratio (LAR) are significant biomarkers associated with poor outcomes in critical illnesses, including sepsis.

  • 2

    Sepsis accounts for approximately 19.7% of all global deaths, with varying mortality rates influenced by healthcare accessibility and quality.

  • 3

    Prior studies indicate that LAR may outperform lactate alone in predicting hospital mortality, but formal verification of this advantage is lacking.

  • 4

    This study utilizes the eICU Collaborative Research Database to investigate the association between lactate, LAR, and 28-day mortality in sepsis patients.

  • 5

    The research employs advanced statistical methods and machine learning techniques to formally compare the prognostic utility of lactate and LAR.
