A propensity score was calculated from six variables: age, BMI, PESI, ESC risk class, Composite PE Shock score and need for systemic thrombolysis. Multivariable regression models were fitted within the propensity score matched sample incorporating matching variables as interaction factors for a doubly robust estimate. Marginal means and marginal odds ratios were computed using \u201cATE\u201d (average treatment effect) as the target estimand along with calculation of cluster-robust standard errors.\n                      <jats:italic>P<\/jats:italic>\n                      -values were adjusted for multiple comparisons using the Benjamini-Hochberg procedure.

CDE, CDT and SPE were performed in 21 (17.2%), 11 (9.0%) and 11 (9.0%) cases. In matched analyses, receipt of any advanced therapy (compared to anticoagulation alone) was associated with increased RVOT VTI (4.6\u2005cm;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.009) and RV \u015a (2.0\u2005cm\/s;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.006) as well as higher odds of TR grade improvement (marginal OR: 3.0;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.002).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Receipt of advanced therapies for acute PE was associated with statistically significant improvement in echocardiographic parameters of RV function at outpatient follow-up (median 26 weeks) among survivors of acute PE compared to systemic anticoagulation alone.
