Survival analysis in dengue hemorrhagic fever using Cox proportional hazard model


Survival analysis is a statistical procedure used to analyze the distribution of time to event data. Dengue hemorrhagic fever data has characteristics that suitable for survival analysis. This study presents a survival analysis to identify the correlation between the times of event of dengue hemorrhagic fever with the measured independent variables by using Cox proportional hazard model. The hazard ratio for platelets obtained that the recovery rate of the patients of dengue hemorrhagic fever with below normal platelet is 2.625 times to the normal platelet count. The result indicated that patients with below normal platelet counts would need a long time to recovery compared than patients with normal platelet counts.
