Survival Extrapolation In The Presence Of Cause Specific Hazards
(John Wiley and Sons Ltd, 2014)
Could albumin level explain the higher mortality in hemodialysis patients with pulmonary hypertension?
(2012-08-08)
Background: The pathogenesis of pulmonary hypertension (PH) in hemodialysis is still unclear. The aim of thisstudy was to identify the risk factors associated with the presence of PH in chronic hemodialysis patients and ...
Un frailty aditivo en modelos de supervivencia bivarianteUn frailty aditivo en modelos de supervivencia bivariante
(2009-02-18)
Bivariate survival models based on the presence of an unobseved random covariate, grailty, tend to assume a proportional hazard hypothesis. A bivariate survival model is constructed. It is based on frailty model that acts ...
Absence of RKIP expression is an independent prognostic biomarker for gastric cancer patients
(2013-02-01)
Gastric cancer is a leading cause of cancer-related mortality, and the presence of lymph node metastasis an important prognostic factor. Downregulation of RKIP has been associated with tumor progression and metastasis in ...
Bayesian survival model induced by frailty for lifetime with long-term survivors
(Wiley-Blackwell, 2021-02-05)
It is introduced the proportional hazards frailty model to allow a discrete distribution for the frailty variable. Frailty zero can be interpreted as being immune or cured. It is defined a class of survival models induced ...
