In peru, reporting male sex partners imparts significant risk of incident HIV/sexually transmitted infection: All men engaging in same-sex behavior need prevention services
(Wolters Kluwer Health, 2013)
Background: Detailed information on the sexual behavior of bisexual, non–gay-identified men and the relationship between same-sex behavior and HIV/sexually transmitted infection (STI) incidence is limited. This study ...
A semi-Markov multistate model for estimation of the mean quality-adjusted survival for non-progressive processes
(SPRINGER, 2009)
We discuss the estimation of the expected value of the quality-adjusted survival, based on multistate models. We generalize an earlier work, considering the sojourn times in health states are not identically distributed, ...
Estimation of the mean quality-adjusted survival using a multistate model for the sojourn times
(ELSEVIER SCIENCE BV, 2008)
In clinical trials, it may be of interest taking into account physical and emotional well-being in addition to survival when comparing treatments. Quality-adjusted survival time has the advantage of incorporating information ...
Modelo logístico generalizado dependente do tempo com fragilidade
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2011-02-11)
Several authors have preferred to model survival data in the presence of covariates through the hazard function, a fact related to its interpretation. The hazard function describes as the instantaneous average of failure ...
Modelos de sobrevivência de longa-duração : uma abordagem unificada
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2008-06-13)
In survival analysis some studies show a meaningful cure rate after treatment followup, so considering standard survival models can not be appropriate. In this work is extended the long-term survival model proposed by Chen, ...
Anemia at one year is an independent risk factor of graft survival
(2012-02-01)
Background Post-transplant anemia is multifactorial and highly prevalent. Some studies have associated anemia with mortality and graft failure. The purpose of this study was to assess whether the presence of anemia at 1 ...
