BACKGROUND Refractory coeliac disease is a severe complication of coeliac disease with heterogeneous outcome. AIM To create a prognostic model to estimate survival of patients with refractory coeliac disease. METHODS We evaluated predictors of 5-year mortality using Cox proportional hazards regression on subjects from a multinational registry. Bootstrap resampling was used to internally val...
Based on the increasing property of ratio of average reversed hazard rates of two non-negative random variables a new stochastic order for the sake of comparison of two lifetime distributions is proposed. This stochastic order admits some distinguishing properties. In order to illustrate the obtained results, a semi-parametric model which is called reverse hazard power and a mixture model of pr...
This study employs a semi-parametric Cox proportional hazard model to study the relationship between survival time and bank-specific determinants of failure of commercial and agricultural banks during the recent recessionary period. Results indicate that non-performing consumer and commercial loans have seriously impaired banks‟ financial health and survival.
The Association between Depression and Medication Nonpersistence in New Users of Antidiabetic Drugs.
OBJECTIVES To measure the association between depression and nonpersistence with antidiabetic drugs (ADs) among new users of oral ADs and to estimate factors associated with nonpersistence among these new users with depression. METHODS We used administrative claims data to identify an adult cohort (≥18 years) of new oral AD users who were free of depression. We followed the patients from AD i...
The results of a Monte Carlo study of the size and power of parametric and semiparametric approaches to inference on covariate effects in survival (time-to-events) models in the presence of model misspecification and an independent censoring mechanism are reported. Basic models employed are a parametric model, where both a baseline distribution and the dependence structure of covariates on the ...
BACKGROUND Diabetes is the most common risk factor for end-stage renal disease (ESRD) and has been associated with increased risk of death. In order to better understand the influence of diabetes on outcomes in hemodialysis, we examine the risk of death of diabetic participants in the HEMODIALYSIS (HEMO) study. METHODS In the HEMO study, 823 (44.6%) participants were classified as diabetic. U...
Erdheim-Chester disease (ECD) is a rare form of non-Langerhans histiocytosis, with noncodified therapeutic management and high mortality. No treatment has yet been shown to improve survival in these patients. We conducted a multicenter prospective observational cohort study to assess whether extraskeletal manifestations and interferon-α treatment would influence survival in a large cohort of EC...
The goal of relative survival methodology is to compare the survival experience of a cohort with that of the background population. Most often an additive excess hazard model is employed, which assumes that each person's hazard is a sum of 2 components--the population hazard obtained from life tables and an excess hazard attributable to the specific condition. Usually covariate effects on the e...
The Cox model is the model of choice when analyzing right-censored and possibly left-truncated survival data. The present paper proposes a program to estimate the hazard function in a proportional hazards model and also to treat more complex observation schemes involving general censored and left-truncated data. The hazard function estimator is defined non-parametrically as the function which m...
