Distinguishing between DIC phenotypes poses a significant challenge. This study aims to apply unsupervised machine learning (ML) algorithms to stratify DIC patients, thereby enabling more personalized treatment approaches.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      We conducted a retrospective analysis of patients diagnosed with DIC upon admission to the ICU at a comprehensive teaching tertiary hospital in China, spanning from May 2015 to November 2022. We applied an unsupervised machine learning approach for consensus clustering using the R package Consensus Cluster Plus to identify clinical phenotypes in 134 patients with DIC. The analysis incorporated the key variables: Thrombin-Antithrombin Complex (TAT), Plasmin-\u03b1\n                      <jats:sub>2<\/jats:sub>\n                      -Plasmin Inhibitor Complex (PIC), tissue plasminogen activator-inhibitor complex (tPAIC), and thrombomodulin (TM). The elbow method, cumulative distribution function (CDF) plot, and consensus matrix were employed to ascertain the optimal number of clusters. Logistic regression (LR) analysis was used to investigate the association between the identified phenotypes and clinical endpoints.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The consensus cluster analysis delineated two distinct subtypes: a mild coagulation dysfunction subtype (n = 79) and a severe coagulation dysfunction subtype (n = 55). Notable differences were observed in both variables included in the analysis (e.g., thrombin-antithrombin complex [TAT],\n                      <jats:italic>P &amp;lt; 0.05<\/jats:italic>\n                      ) and those not utilized for model training (e.g., heart rate [HR]\n                      <jats:italic>P &amp;lt; 0.05<\/jats:italic>\n                      and systolic blood pressure [SBP]\n                      <jats:italic>P &amp;lt; 0.05<\/jats:italic>\n                      ). Logistic regression revealed that the severe coagulation dysfunction subtype was significantly associated with increased odds of 7-day (OR 4.71; 95% CI 2.23\u20139.98;\n                      <jats:italic>P &amp;lt; 0.001<\/jats:italic>\n                      ), 28-day (OR 2.29; 95% CI 1.11\u20134.72;\n                      <jats:italic>P = 0.024<\/jats:italic>\n                      ).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The study identified two clusters with distinct laboratory profiles and mortality risk.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fmolb.2026.1699476","type":"journal-article","created":{"date-parts":[[2026,2,25]],"date-time":"2026-02-25T07:06:13Z","timestamp":1772003173000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Uncovering distinct clinical phenotypes in disseminated intravascular coagulation through machine learning-enabled cluster analysis"],"prefix":"10.3389","volume":"13","author":[{"given":"Qingbo","family":"Zeng","sequence":"first","affiliation":[{"name":"Intensive Care Unit, The 908th Hospital of Chinese PLA Logistic Support Force","place":["Nanchang, China"]},{"name":"Intensive Care Unit, Nanchang Hongdu Hospital of Traditional Chinese Medicine","place":["Nanchang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junjie","family":"Zeng","sequence":"additional","affiliation":[{"name":"Intensive Care Unit, The 908th Hospital of Chinese PLA Logistic Support Force","place":["Nanchang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingwei","family":"Lin","sequence":"additional","affiliation":[{"name":"Intensive Care Unit, The 908th Hospital of Chinese PLA Logistic Support Force","place":["Nanchang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lincui","family":"Zhong","sequence":"additional","affiliation":[{"name":"Intensive Care Unit, The 908th Hospital of Chinese PLA Logistic Support Force","place":["Nanchang, China"]},{"name":"Nanchang Key Laboratory of Thrombosis and Hemostasis","place":["Nanchang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Longping","family":"He","sequence":"additional","affiliation":[{"name":"Intensive Care Unit, The 908th Hospital of Chinese PLA Logistic Support Force","place":["Nanchang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jingchun","family":"Song","sequence":"additional","affiliation":[{"name":"Intensive Care Unit, The 908th Hospital of Chinese PLA Logistic Support Force","place":["Nanchang, China"]},{"name":"Nanchang Key Laboratory of Thrombosis and Hemostasis","place":["Nanchang, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,2,25]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"803","DOI":"10.1111\/bjh.17172","article-title":"Disseminated intravascular coagulation: epidemiology, biomarkers, and management","volume":"192","author":"Adelborg","year":"2021","journal-title":"Br.
