Inverse probability of treatment weighting (IPTW) was employed to rigorously balance baseline confounders. The primary endpoint was NACE. The incremental predictive value of the joint trajectories was assessed using the C-index, continuous net reclassification improvement (cNRI), and integrated discrimination improvement (IDI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 736 patients (71 NACE events during follow-up), four distinct joint trajectory groups were identified: Double Stable (\n                      <jats:italic>n<\/jats:italic>\n                      \u202f=\u202f329), BP-Fluctuating (\n                      <jats:italic>n<\/jats:italic>\n                      \u202f=\u202f215), RHR-Fluctuating (\n                      <jats:italic>n<\/jats:italic>\n                      \u202f=\u202f108), and Double Fluctuating (\n                      <jats:italic>n<\/jats:italic>\n                      \u202f=\u202f84).
