ABSTRACT
This brief note describes the principles of survival analysis. Survival analysis is method for studying the time between entry to a study and a subsequent event and is used frequently in neurointervention studies. Kaplan-Meier estimator is nonparametric method for estimating the survival curve and log rank test is used for comparing between exposure and non-exposure groups. Proportional hazards model, a semi-parametric regression model specifically developed for censored data, is used when there are many exposure variables.
