joint modeling of longitudinal and time-to-event data

Joint modeling of longitudinal and time-to-event data is one of the most rapidly evolving areas of current biostatistics research, with several extensions of the standard joint model presented here already proposed in the literature. The study uses multivariate joint modeling of longitudinal and time to event data to establish the relationship between longitudinal biomarker measurements and the duration to relapse. CD4 count can also be used when immunological failure is suspected as we have shown that it is associated with mortality. Poor CD4 recovery and risk of subsequent progression to AIDS or death despite viral suppression in a South African cohort. Many joint modeling approaches have been proposed to handle different types of longitudinal biomarkers and survival outcomes. See this image and copyright information in PMC.

Joint modelling enabled the assessment of the effect of longitudinal CD4 count on mortality while correcting for shared random effects between longitudinal and time-to-event models. Advancements in computation and availability of adequate software helped to promote the use of joint modeling longitudinal and time to event data in the field of biology and health research , . This package fits shared parameter models for the joint modeling of normal longitudinal responses and event times under a Bayesian approach. We studied 4014 patients from the Centre for the AIDS Programme of Research in South Africa (CAPRISA) who initiated ART between June 2004 and August 2013. Various options for the survival model and the association structure areprovided. The main purpose of doing longitudinal and time to event data is to analyze the relationship between the longitudinal pattern of a covariate and duration to the event of interest.

The impact of delayed switch to second-line antiretroviral therapy on mortality, depending on failure time definition and CD4 count at failure. In particular, joint modeling approaches aim at characterizing the joint distribution of the longitudinal outcomes and the time‐to‐event data in different ways depending on the framework to avoid the bias and loss of efficiency that can appear in separate treatments. We used proportional hazards regression model to assess the effect of baseline characteristics (excluding CD4 count) on mortality, and linear mixed effect models to evaluate the effect of baseline characteristics on the CD4 count evolution over time.
