Survival analysis
Research Methods
Definition. Survival analysis is a set of methods for analysing time until an event, such as death, discharge or readmission, while handling censored observations.
Explanation
Introductory guides explain Kaplan-Meier curves, log-rank tests and Cox models (Denfeld et al., 2023). Interpretable survival models are now used to analyse hospital length of stay (Li et al., 2025).
