Clinical and laboratory data were collected.

The area under the curve (AUC) of G\u201017, PRECISE\u2010DAPT scores alone, and in combination were 0.734, 0.794, and 0.844, respectively; the AUC further increased to 0.878 after incorporating ticagrelor exposure, indicating that the combined assessment with ticagrelor exposure has superior exploratory value in identifying high\u2010risk patients with UGIB (\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.05).

Given the retrospective single\u2010center design and limited sample size, these findings remain preliminary and require prospective multicenter validation.<\/jats:p>\n
