Propensity score matching balanced baseline characteristics. UFH was administered intravenously and LMWH subcutaneously at standard doses. Twenty\u2010two biomarkers were assessed at baseline and days 1, 3, and 7 post\u2010anticoagulation. Survival and bleeding were evaluated using Kaplan\u2013Meier curves. Generalized linear mixed models identified treatment\u2010associated biomarkers, and mediation analysis evaluated their role in survival benefit.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      After matching, 109 and 394 patients were included in the UFH and LMWH comparisons, respectively. Both UFH and LMWH were associated with significantly improved survival versus the no anticoagulation group (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001), without increased 90\u2010day bleeding risk. UFH was associated with significant reductions in FDP, D\u2010dimer, IL\u20106, IL\u20108, and CRP (FDR\u2010adjusted\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001), whereas LMWH was associated with significant reductions only in FDP and D\u2010dimer. Mediation analysis demonstrated that UFH's survival benefit was partly mediated by IL\u20106 and IL\u20108 reduction, accounting for 30.9% (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.012) and 29.6% (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.045) of the total effect.
