Multivariate model

Default: 6 covariates · N=226, events=80 · 13.3 events/covariate

Covariate	HR (95% CI)	p
Residual AR (any vs none)	1.366 (0.866–2.154)	0.1796
Age	0.935 (0.780–1.121)	0.4684
EuroSCORE II	1.047 (1.021–1.073)	0.0003
LVEF pre-ViV	0.859 (0.752–0.982)	0.0261
Post-ViV gradient	0.886 (0.763–1.030)	0.1146
TAVI-first (vs SAVR-first)	1.754 (0.928–3.316)	0.0836

Interactive: select covariates

Every change is sent to the backend, which reruns the Cox model on the full dataset and returns the result (POST /api/multivariate). Listwise deletion: only patients with data for every selected covariate are included.
