was performed using the Kaplan-Meier method for univariate analysis and Cox regression for multivariate analysis.
In either case, survival analysis
is a method where a time to an event, such as death or equipment failure, is measured and modeled.

We used a set of statistical techniques called survival analysis
, specifically Cox regression (Cox, 1972) and Kaplan-Meier analysis to study the impact of the independent variables on probability of turnover and employee tenure.
In a survival analysis
that controlled for men's background characteristics and sexual behaviors, the adjusted hazard ratio of HIV acquisition among circumcised men was 0.
Univariate (Kaplan-Meier) and multivariable (Cox model) survival analysis
were performed, using disease-specific mortality as an endpoint.
