A multivariate survival model induced by discrete frailty
(Taylor & Francis Inc, 2020-08-11)
Frailty models are generally used to model heterogeneity and dependence between individuals. The distribution of the frailty variable is often assumed to be continuous. However, there are situations where a discretely-distributed ...
Frailty And Depressive Symptoms In Older Adults: Data From The Fibra Study - Unicamp
(Springer Int PublishingCham, 2016)
Survival model induced by discrete frailty for modeling of lifetime data with long-term survivors and change-point
(Taylor & Francis Inc, 2019-07-30)
Frailty models are used for modeling heterogeneity in the data analysis of lifetimes. Analysis that ignore frailty when it is present leads to incorrect inferences. In survival analysis, the distribution of frailty is ...
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 ...
A frailty modeling approach for parental effects in animal breeding
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2011)
Survival models involving frailties are commonly applied in studies where correlated event time data arise due to natural or artificial clustering. In this paper we present an application of such models in the animal ...
Systematic Review Of The Kihon Checklist: Is It A Reliable Assessment Of Frailty?
(Wiley-BlackwellHoboken, 2016)
Frailty and reduced gait speed are independently related to mortality of cirrhotic patients in long-term follow-up
(Elsevier, 2021)
ntroduction and objectives: Frailty is characterized by a poor restoration of homeostasis after a stressor
event. Although it is not usually diagnosed, it has been associated with decreased survival in cirrhotic
patients. ...
Frequency of frailty and its association with cognitive status and survival in older Chileans
(Dove Medical Press Ltd., 2017)
© 2017 Albala et al.Background: Age-associated brain physiologic decline and reduced mobility are key elements of increased age-associated vulnerability. Objective: To study the frequency of frailty phenotype and its ...
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 ...
Nutritional interventions for the management of frailty in older adults: systematic review and meta-analysis of randomized clinical trials
(2021-07-07)
CONTEXT: Although nutrition is considered an important intervention for the management of frailty, the actual effectiveness of interventions addressing nutrition in frail older people remains unclear. OBJECTIVE: The aim ...
