eff ect of risk factors on mortality, we did Cox proportional hazards regression. Interaction analysis from the Cox regression was not specifi ed in the protocol; it was done in the 1-year analyses and presented in the pre-market approval submission; the same subgroups are considered here. We also used Cox regression for multivariable analysis, in which we used multiple imputations to accommodate missing baseline variables. The multivariable models included covariates with a p value of less than 0·20 in univariate analyses. We did an additional time-dependent covariate analysis to test the association of complications during TAVR or SAVR with subsequent mortality. The primary and key secondary endpoint analyses in the protocol were for non-inferiority at 1 year; no such analyses were specifi ed for 5 years, and no such analyses are presented in this report. We did landmark analyses including all patients alive at the start point of the analyses;
the landmark analyses were not prespecifi ed. We did all statistical analyses with SAS (version 9.3).
This study is registered with ClinicalTrials.gov, NCT00530894.
Role of the funding sourceThe funder designed and monitored the study and participated in the selection and management of the study sites and data collection. The funder had no role in data analysis or interpretation, or the writing of the report. MJM and the executive committee had unrestricted access to the data after the database was locked and had full responsibility for the decision to submit for publication.
ResultsWe screened 3105 patients, of whom 699 were enrolled: 348 assigned to TAVR and 351 assigned to SAVR (fi gure 1).

Conclusions• NOTION is the first trial to report on 5-year outcomes after TAVR vs. SAVR in lower risk patients
(82% with STS < 4%)• After 5 years, there were no differences in all-cause mortality, stroke, myocardial infarction, or
these combined• There was no difference in prosthetic valve re-intervention• Prosthetic opening area was larger and mean gradient lower for TAVR and remained unchanged
over time• TAVR continued to have more mild/moderate prosthetic regurgitation• New pacemaker implantation after TAVR trended to be associated with increased mortality• Determining the longevity of TAVR prostheses will require longer term follow-up
