Time-to-event analysis

Perspectives in Clinical Research
Survival analysis (or time-to-event analysis) deals with data where the outcome of interest is the length of time until the occurrence of an event. This type of analysis is unique because the event may not occur in all participants (known as censoring ...

Bayesian Mediation Analysis for Time-to-Event Outcome: Investigating Racial Disparity in Breast Cancer Survival. [PDF]

Commun Stat Theory Methods
Mediation analysis is conducted to make inferences on the effects of mediators that intervene in the relationship between an exposure variable and an outcome. Bayesian mediation analysis (BMA) naturally considers the hierarchical structure of the effects

Effect of real-time and post-event feedback in out-of-hospital cardiac arrest attended by EMS — A systematic review and meta-analysis

Resuscitation Plus, 2021
Objectives: A systematic review to determine if cardiopulmonary resuscitation (CPR) guided by either real-time or post-event feedback could improve CPR quality or patient outcome compared to unguided CPR in out-of-hospital cardiac arrest (OHCA). Methods:

An improved method for the effect estimation of the intermediate event on the outcome based on the susceptible pre-identification

BMC Medical Research Methodology, 2021
Background In follow-up studies, the occurrence of the intermediate event may influence the risk of the outcome of interest. Existing methods estimate the effect of the intermediate event by including a time-varying covariate in the outcome model ...

A post-pandemic reflection of the changing role of contemporary event professionals: Implications for event professionals and higher education [PDF]

, 2023
While the event, tourism, and hospitality industry is constantly evolving, COVID-19 vastly shifted the roles, responsibilities, and jobs for event professionals, which caused event management educators to reevaluate their curriculum and course offerings.

Time-dependent event accumulation in a cardiovascular outcome trial of patients with type 2 diabetes and established atherosclerotic cardiovascular disease

Cardiovascular Diabetology, 2023
Background Estimating cardiovascular (CV) event accrual is important for outcome trial planning. Limited data exist describing event accrual patterns in patients with type 2 diabetes (T2D).

A Parameterized Algebra for Event Notification Services [PDF]

, 2002
Event notification services are used in various applications such as digital libraries, stock tickers, traffic control, or facility management. However, to our knowledge, a common semantics of events in event notification services has not been defined so

Generalised verification of the observer property in discrete event systems [PDF]

, 2012
The observer property is an important condition to be satisfied by abstractions of Discrete Event Systems (DES) models. This paper presents a generalised version of a previous algorithm which tests if an abstraction of a DES obtained through natural ...

Are non-constant rates and non-proportional treatment effects accounted for in the design and analysis of randomised controlled trials? A review of current practice

BMC Medical Research Methodology, 2019
Background Most clinical trials with time-to-event primary outcomes are designed assuming constant event rates and proportional hazards over time. Non-constant event rates and non-proportional hazards are seen increasingly frequently in trials.

Time-to-Event Analysis with Unknown Time Origins via Longitudinal Biomarker Registration

, 2022
In observational studies, the time origin of interest for time-to-event analysis is often unknown, such as the time of disease onset. Existing approaches to estimating the time origins are commonly built on extrapolating a parametric longitudinal model ...
