SURVIVAL--an integrated software package for survival curve estimation and statistical comparison of survival rates of two groups of patients or experimental animals.
SURVIVAL, a new integrated software package for survival curve estimation and statistical comparison of survival rates of two censored or uncensored groups of patients or experimental animals, is described and demonstrated. The software is based on the calculation of the Kaplan-Meier estimates of survival curves and utilizes the Mantel-Haenszel and/or Fisher's test for the statistical comparison of the corresponding survival rates. SURVIVAL can be used for statistical evaluation of survival data obtained either on sequentially created or fixed size groups. The software is menu driven to provide a very user friendly tool for analyzing survival data. It may be of great value mainly in clinical use because it automatically enables evaluation of a large set of survival data, sequentially collected in SURVIVAL's own database during a long survival study, with entry and evaluation possible at any time during the study.
