The survival in a group of patients is calculated using a Kaplan-Meier curve and the hypothesis that the survival can be predicted by a specified Cox hazard is studied. This Cox hazard is obtained from a previous study of similar patients. A simple test of the hypothesis is constructed by comparing a suitable average of the individual predicted survival curves with the observed survival. Three averaging procedures are presented; "direct adjusted survival curve", "Bonsel's survival curve" and "expected survival curve". Consistency and asymptotic distribution properties of the comparisons are discussed
