This paper outlines the methodology and statistical approaches, such as proportional hazards analysis, used in a large UK multicentre heart valve registry to evaluate long-term valve performance and patient survival.
Drury et al. (1992) conducted an observational in Heart valve implant (n=16,000). Heart valve implants was evaluated. A multicentre database comprising over 16,000 heart valve implants across 22 UK centres enables in-depth statistical analysis of survival and event-free survival.
