SURVIVAL ANALYSIS AND LENGTH-BIASED SAMPLING
Croatian Operational Research Review, 2010 When survival data are colleted as part of a prevalent cohort study, the recruited cases have already experienced their initiating event. These prevalent cases are then followed for a fixed period of time at the end of which the subjects will either have

Arthritis &Rheumatology, EarlyView.Objective Spondyloarthritides (SpA) and inflammatory bowel disease (IBD) are immune‐mediated diseases with overlap in clinical and immunologic features. However, temporal correlation of SpA and IBD in individual patients and risk factors are not well characterized.

p3state.msm: Analyzing Survival Data from an Illness-Death Model
In longitudinal studies of disease, patients can experience several events across a followup period. Analysis of such studies can be successfully performed by multi-state models.

Association of Clonal Hematopoiesis With Incident, Late‐Onset, Seropositive Rheumatoid Arthritis
Arthritis &Rheumatology, EarlyView.Objective Clonal hematopoiesis (CH), defined by acquired driver mutations in hematopoietic stem cells, is associated with many inflammatory diseases of aging. We investigated whether CH and its subtypes, CH of indeterminate potential (CHIP) and mosaic chromosomal alteration (mCA), are associated with incident rheumatoid arthritis (RA) and whether ...

Estimating panel data duration models with censored data
, 2005 This paper presents a method for estimating a class of panel data duration models, under which an unknown transformation of the duration variable is linearly related to the observed explanatory variables and the unobserved heterogeneity (or frailty ...

Arthritis &Rheumatology, EarlyView.Objective Disease activity plays a central role in rheumatoid arthritis (RA) clinical studies. The inconsistent availability of data on disease activity in real‐world electronic health records (EHRs) data has limited the ability to generate real‐world evidence (RWE).

Beta-Stacy survival regression models [PDF]
, 2007 This paper introduces a class of survival models for discrete time-to-event data with random right censoring. Flexible distributions for the survival times are constructed by modelling the random survival functions as discrete-time beta-Stacy processes (

British Journal of Clinical Pharmacology, EarlyView.Aims Predetermined treatment duration limits (PTDLs) are often used by Taiwan's National Health Insurance Administration to contain healthcare costs, but they may compromise patient outcomes. Therefore, we studied Taiwan's 2017 extension of the bevacizumab PTDL from 24 to 36 weeks in metastatic colorectal cancer (mCRC) to evaluate whether prolonged ...

A scoping review of survival analysis methods for doubly interval censored data
Discover Applied SciencesDoubly interval-censored data (DICD) often emerge in longitudinal studies, where the survival time, T = W − V, denotes the duration between two connected events: the initial event time (V) and the subsequent event time (W), both of which are subject to ...

Estimation of Discrete Time Duration Models with Grouped Data [PDF]
Dynamic discrete choice panel data models have received a great deal of attention. In those models, the dynamics is usually handled by including the lagged outcome as an explanatory variable.
