Competing risk models to estimate the excess mortality and the first recurrent-event hazards [PDF]

open access: yesBMC Medical Research Methodology, 2011
Background In medical research, one common competing risks situation is the study of different types of events, such as disease recurrence and death. We focused on that situation but considered death under two aspects: "expected death" and "excess death",

Estimations of accelerated Lomax lifetime distribution with a dependent competing risks model under type-I generalized hybrid censoring scheme

open access: yesAlexandria Engineering Journal, 2022
In a reliability theory, the statistical inference under accelerated competing risks model have a great significance. This model proposes the assumption of independence of variables for convenience.

Analysis of Prognostic Factors of Low-Grade Gliomas in Adults Using Time-Dependent Competing Risk Models: A Population Study Based on the Surveillance, Epidemiology, and End Results Database

open access: yesCancer Control, 2022
Background Because of multiple competing death outcomes and time-varying coefficients, using a Cox regression model to analyze the prognostic factors of low-grade gliomas (LGG) may lead to a possible bias.

Loss to follow-up as a competing risk in an observational study of HIV-1 incidence. [PDF]

open access: yesPLoS ONE, 2013
Conventional survival estimates may be biased if loss to follow-up (LTF) is associated with the outcome of interest. Our goal was to assess whether the association between sexual risk behavior and HIV-1 acquisition changed after accounting for LTF with ...

Inference about time-dependent prognostic accuracy measures in the presence of competing risks

open access: yesBMC Medical Research Methodology, 2020
Background Evaluating a candidate marker or developing a model for predicting risk of future conditions is one of the major goals in medicine. However, model development and assessment for a time-to-event outcome may be complicated in the presence of ...

Identification of a competing risks model with unknown transformations of latent failure times [PDF]

open access: yes, 2005
This paper is concerned with identification of a competing risks model with unknown transformations of latent failure times. The model in this paper includes, as special cases, competing risks versions of proportional hazards, mixed proportional ...

Competing risks models and time-dependent covariates [PDF]

open access: yes, 2008
New statistical models for analysing survival data in an intensive care unit context have recently been developed. Two models that offer significant advantages over standard survival analyses are competing risks models and multistate models.

Statistical analysis and application of competing risks model with regression

open access: yesCroatian Operational Research Review, 2019
The paper deals with the methods of statistical analysis of dependent competing risks in the presence of covariates. The problem of identification of marginal and joint distributions of competing random variables is recalled and certain ...

Makeham mortality models as mixtures: Advancing mortality estimations through competing risks frameworks [PDF]

open access: yesDemographic Research
BACKGROUND: The Makeham term serves as a fundamental component in mortality modeling, offering a constant additive hazard that accounts for background mortality factors usually unrelated to the aging process.

Simulation shows undesirable results for competing risks analysis with time-dependent covariates for clinical outcomes

open access: yesBMC Medical Research Methodology, 2018
Background We evaluate three methods for competing risks analysis with time-dependent covariates in comparison with the corresponding methods with time-independent covariates.
