Survival analysis of thalassemia major patients using Cox, Gompertz proportional hazard and Weibull accelerated failure time models
Background: Thalassemia major (TM) is a severe disease and the most common anemia worldwide. The survival time of the disease and its risk factors are of importance for physicians. The present study was conducted to apply the semi-parametric Cox PH model and use parametric proportional hazards (PH) and accelerated failure time (AFT) models to identify the risk factors related to survival of TM ...
متن کاملAnimal Models Of Liver Cirrhosis And Fibrosis
Animal modeling is a crucial necessity in clinical studies of liver diseases. Authenticity of the data which are produced using this tool under different conditions and accuracy of the analyses and assessments which would be based on such data sets is completely dependent on the adoption of a standardized methodology for analyzes and assessment of these data sets. Cirrhosis and Fibrosis are amo...
متن کاملa comparison between accelerated failure-time and cox pro-portional hazard models in analyzing the survival of gastric cancer patients
background : gastric cancer is the one of the most prevalent reason of cancer-related death in the world. survival of patients after surgery involves identifying risk factors. there are various models to detect the effect of risk factors on patients’ survival. the present study aims at evaluating these models. methods : data from 330 gastric cancer patients diagnosed at the iran cancer institut...
متن کاملStructural accelerated failure time models for survival analysis in studies with time-varying treatments.
BACKGROUND In the absence of unmeasured confounding factors and model misspecification, standard methods for estimating the causal effect of time-varying treatments on survival are biased when (i) there exists a time-dependent risk factor for survival that also predicts subsequent treatment and (ii) past treatment history predicts subsequent risk factor level. In contrast, structural models pro...
متن کاملHeart transplantation in patients with liver cirrhosis.
OBJECTIVE Liver cirrhosis is considered to be a contraindication to heart transplantation. However, the clinical outcome of heart transplantation in patients with liver cirrhosis has not been reported. Here, we sought to evaluate the clinical outcome of heart transplantation in cirrhotic patients. METHODS Data were collected by retrospective chart review. Patients with liver cirrhosis at the ...
