Estimating cumulative incidence functions in competing risks data with dependent left‐truncation [PDF]

open access: yesStatistics in Medicine, 2019
Both delayed study entry (left‐truncation) and competing risks are common phenomena in observational time‐to‐event studies. For example, in studies conducted by Teratology Information Services (TIS) on adverse drug reactions during pregnancy, the natural time scale is gestational age, but women enter the study after time origin and upon contact with ...

Incidence of Long‐Term Structural Valve Dysfunction and Bioprosthetic Valve Failure After Transcatheter Aortic Valve Replacement

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background Long‐term data on durability of currently available transcatheter heart valves are sparse. We sought to assess the incidence of long‐term (8‐year) structural valve dysfunction and bioprosthetic valve failure in a cohort of patients with ...

Statistical methods to derive efficacy estimates of anti-malarials for uncomplicated Plasmodium falciparum malaria: pitfalls and challenges

open access: yesMalaria Journal, 2017
The Kaplan–Meier (K–M) method is currently the preferred approach to derive an efficacy estimate from anti-malarial trial data. In this approach event times are assumed to be continuous and estimates are generated on the assumption that there is only one

AN ADDITIVE SUBDISTRIBUTION HAZARDS MODEL FOR COMPETING RISKS DATA

open access: yesMedia Statistika
Competing risk failure time data occur frequently in medical a number of methods have been proposed for the analysis of these data. The classic approach is to model all cause-specific hazards and then estimate the cumulative incidence curve based on ...

Prevalence and cumulative incidence of autism spectrum disorders and the patterns of co-occurring neurodevelopmental disorders in a total population sample of 5-year-old children

open access: yesMolecular Autism, 2020
Backgrounds Whether there is a true increase in autism spectrum disorder (ASD) frequency or not remains unclear. Additionally, the rates of co-existing neurodevelopmental disorders (NDD) in a total population sample has not been fully examined before ...

Nomograms for Estimating Cause-Specific Death Rates of Patients With Inflammatory Breast Cancer: A Competing-Risks Analysis

open access: yesTechnology in Cancer Research & Treatment, 2021
Purpose: Inflammatory breast cancer (IBC) is a rare, aggressive and special subtype of primary breast cancer. We aimed to establish competing-risks nomograms to predict the IBC-specific death (BCSD) and other-cause-specific death (OCSD) of IBC patients ...

Statistical inference methods for cumulative incidence function curves at a fixed point in time [PDF]

open access: yesCommunications in Statistics - Simulation and Computation, 2018
Competing risks data arise frequently in clinical trials. When the proportional subdistribution hazard assumption is violated or two cumulative incidence function (CIF) curves cross, rather than comparing the overall treatment effects, researchers may be interested in focusing on a comparison of clinical utility at some fixed time points.
