    Se realiza un análisis de supervivencia de pacientes que acudían al Servicio de Diálisis Peritoneal del Hospital Clínico Universitario de Caracas, Venezuela, entre los años 1980 y 1997, utilizando la muerte como evento de interés. El análisis incluye: estimaciones de las funciones de supervivencia mediante el estimador de Kaplan-Meier, obtención del mejor modelo semiparamétrico de riesgos proporcionales (modelo de Cox), verificación de los supuestos y análisis de residuos. El modelo de Cox incluye diabetes, edad y el índice de Quetellet como covariables.

    A survival analysis in patients that assisted to the peritoneal dialysis service of the Hospital Clínico Universitario de Caracas, Venezuela, between 1980 y 1997, using death as event of interest is presented. Estimation of the survival function by the Kaplan-Meier estimator, Semi-parametric proportional hazard models (Cox models), verification of the assumptions of the models and residual analysis are included. In the Cox model, diabetes, age and Quetellet" s index are used as covariates.
