The lactate\u2010to\u2010albumin ratio (LAR) is a novel biomarker that reflects both metabolic stress and nutritional\u2010inflammatory status, and it has demonstrated independent prognostic value in various critical illnesses. However, its association with mortality in critically ill patients with T2DM remains unclear. This study aims to evaluate the predictive value of LAR for prognosis in this specific patient population through a retrospective analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective observational cohort study utilized data from the Medical Information Mart for Intensive Care IV (MIMIC\u2010IV) v3.0 database, which includes complete medical records of patients admitted to the intensive care unit (ICU) of a U.S. medical center between 2008 and 2022. Subjects were categorized into three groups based on LAR tertiles. The study assessed ICU mortality and in\u2010hospital mortality as primary outcomes; 30\u2010day, 90\u2010day, and 365\u2010day mortality after ICU admission served as secondary outcomes. Machine learning identified key variables related to LAR and outcomes. The association between LAR and primary outcomes was analyzed using multivariate logistic regression and restricted cubic spline (RCS) regression. Cumulative mortality was analyzed using Kaplan\u2013Meier curves. Threshold effects were evaluated using generalized additive models to enhance clinical applicability. Sensitivity and subgroup analyses were used to validate the robustness of the results and the interactions within subgroups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Result<\/jats:title>\n                    <jats:p>\n                      The study included 5463 critically ill T2DM patients. Using Boruta and SHapley Additive exPlanations (SHAP) algorithms, 14 key variables were identified. RCS analysis revealed a nonlinear relationship between LAR and in\u2010hospital mortality (\n                      <jats:italic>p<\/jats:italic>\n                      for nonlinearity\u2009=\u20090.001). Threshold effect analysis identified a critical LAR threshold of 2.10. Kaplan\u2013Meier survival curves showed that higher LAR values were correlated with increased mortality (\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001).
