Primary (eg, death and stroke) and secondary trial end points were compared across treatment arms (eg, transcatheter aortic valve replacement [TAVR] versus surgical aortic valve replacement [SAVR]) using trial-adjudicated outcomes versus outcomes derived from claims at 1 year (HiR) or 2 years (SURTAVI).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>\n              Among 600 linked HiR participants (linkage rate, 80.0%), the rate of the trial\u2019s primary end point of all-cause mortality occurred in 13.7% of patients receiving TAVR and 16.4% of patients receiving SAVR at 1 year by using both trial data (hazard ratio, 0.84 [95% CI, 0.65\u20131.09];\n              <jats:italic>P<\/jats:italic>\n              =0.33) and claims data (hazard ratio, 0.86 [95% CI, 0.66\u20131.11];\n              <jats:italic>P<\/jats:italic>\n              =0.34; interaction\n              <jats:italic>P<\/jats:italic>\n              value=0.80).
