Existing scoring systems such as the Modified CT Severity Index (MCTSI) primarily rely on imaging features, but alone may not fully reflect inflammatory status, while inflammatory markers like the Lymphocyte-to-Monocyte Ratio (LMR) show potential in predicting disease severity; however, studies combining both are insufficient.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>To investigate the value of integrating LMR with MCTSI to construct a new scoring system (MCTSI-LMR) for early stratification in acute pancreatitis, optimizing clinical predictive efficacy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 216 patients with acute pancreatitis admitted to Hefei Third People\u2019s Hospital from April 2022 to January 2025 were selected as the study subjects. All patients were divided into mild group (65 cases), moderately severe group (108 cases), and severe group (43 cases) according to the Atlanta classification criteria (2012 revision). All patients underwent abdominal CT scanning and complete blood count within 24 hours of admission to calculate MCTSI scores and LMR values. Using clinical outcomes as the gold standard, inter-group indicator differences and the diagnostic efficacy of the combined score were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Based on disease severity, the severe group had significantly lower LMR values than the mild and moderately severe groups (\n                      <jats:italic>t<\/jats:italic>\n                      = 125.473,\n                      <jats:italic>P<\/jats:italic>\n                      &amp;lt; 0.001) and higher MCTSI scores (\n                      <jats:italic>t<\/jats:italic>\n                      = 298.456,\n                      <jats:italic>P<\/jats:italic>\n                      &amp;lt; 0.001).
