Application of survival analysis techniques to evaluation of factors affecting compliance in a clinical trial of hypertension control

Abstract

Survival analysis techniques including follow-up life tables and regression methods that utilize concomitant information are shown to be applicable to the analysis of medical follow-up study dropout data. These techniques have been applied to data from the Hypertension Detection and Follow-up Program in order to gain knowledge about factors associated with a study participant's tendency to either remain active in the Program or drop out.
