Comparisons

Comparison	N	Events	β (SE)	Cox HR (95% CI)	Cox p	Log-rank p	Result
Continuous, per 10 mL	226	79	0.079 (0.035)	1.08 (1.01–1.16)	0.0256	–	Significant
Continuous, per 20 mL	226	79	0.158 (0.071)	1.17 (1.02–1.35)	0.0256	–	Significant
Top vs bottom tertile (data-driven cutoff)	154	58	0.360 (0.269)	1.43 (0.85–2.43)	0.1805	0.1782	Not significant

Tertile cuts: ≤67 mL vs >93 mL.

Kaplan–Meier curve

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.

Post-ViV Echo

Baseline
