    (Addis Abeba university, 2009-07) Keraleme, Abrham; Wencheko, Eshetu(Professer)
    The objective of this study is to estimate survival probabilities and identify the risk factors for the death of tuberculosis patients in Addis Ababa during the treatment period. The data for this study are obtained from TB patients registered during September 2007 to January 2008 under DOTS at the Health Centers in Addis Ababa. The analytical methodologies used were the Kaplan-Meier to estimate the survival time and Cox’s regression model was employed to identify the covariates that have a statistical significant effect on the survival longevity of TB patients. The estimation of the model parameters was done by partial maximum likelihood procedures. From the Cox regression model the factors Age, Initial weight, Category, HIV and interaction of Age by HIV were the risk factors for the death of TB patients. Furthermore it was found that the survival probabilities of TB patients with low initial weight, older age and HIV positive were low
