Standard Computer Programs in Statistical Analysis of Survival in Childhood Lymphoblastic Leukemia
Abstract
A material comprising all children in Sweden with acute lymphoblastic leukemia diagnosed in the years 1973–80 was analysed statistically.
The total number of children was 505. Studies were made of 38 different variables, using frequency tables, cross tables, life table studies (1) and linear regression analysis according to Cox's method (2,4).
Chi-square tests and log rank tests were included in the methods. The combination of life-table studies and linear regression analysis proved to be of value in assessing the significance of different parameters and treatment programs with regard to prognosis.
The aim of this paper is to present a method for analysis of a patient material with use of standard computer programs. The results of the total analysis will be published elsewhere (3).
