Competing Risks and Their Impact on Treatment Efficacy Assessment in Fractionated Stereotactic Radiotherapy for Brain Metastases: A Retrospective Study

Health Science Reports
Background and Aims The Kaplan‐Meier (KM) method and competing risk analysis are two statistical approaches for analyzing time‐to‐event data. These methods differ in their treatment of competing events, such as deaths occurring before the event of ...

Therapeutic Plasma Exchange Protects Patients with Sepsis-Associated Disseminated Intravascular Coagulation by Improving Endothelial Function

Clinical and Applied Thrombosis/Hemostasis, 2021
The mortality rate of sepsis-associated disseminated intravascular coagulation (DIC) is high. This study aimed to explore the efficacy of therapeutic plasma exchange (TPE) in sepsis-associated DIC patients by improving endothelial function.

Flexible parametric modelling of cause-specific hazards to estimate cumulative incidence functions [PDF]

BMC Medical Research Methodology, 2013
Competing risks are a common occurrence in survival analysis. They arise when a patient is at risk of more than one mutually exclusive event, such as death from different causes, and the occurrence of one of these may prevent any other event from ever happening.There are two main approaches to modelling competing risks: the first is to model the cause ...

Brief Report: A Multidisciplinary Initial Workup for Suspected Lung Cancer as Fast-Track Intervention to Histopathologic Diagnosis

JTO Clinical and Research Reports, 2023
Guidelines for optimal timing of lung cancer diagnosis and treatment have been implemented in many countries, but the effect of fast-track interventions on the shortening of time interval is still debatable.

Approximate tests for the equality of two cumulative incidence functions of a competing risk

Statistics, 2017
In the context of a competing risks set-up, we discuss different inference procedures for testing equality of two cumulative incidence functions, where the data may be subject to independent right-censoring or left-truncation. To this end, we compare two-sample Kolmogorov–Smirnov- and Cramér–von Mises-type test statistics.

Parametric methods for estimating survival in continuous ambulatory peritoneal dialysis patients in the presence of competing events

Journal of Biostatistics and Epidemiology, 2015
Background & Aim: In many studies, the survival of patients with chronic kidney disease who are treated with peritoneal dialysis technique has been considered, while this is possible in peritoneal dialysis  patients  to switch  to another  treatment.  To

Outcomes of an Inpatient Dialysis Start in Patients With Kidney Graft Failure: A Population-Based Multicentre Cohort Study

Canadian Journal of Kidney Health and Disease, 2021
Background: The frequency and outcomes of starting maintenance dialysis in the hospital as an inpatient in kidney transplant recipients with graft failure are poorly understood.

Inference for cumulative incidence functions with informatively coarsened discrete event‐time data [PDF]

Statistics in Medicine, 2008
AbstractWe consider the problem of comparing cumulative incidence functions of non‐mortality events in the presence of informative coarsening and the competing risk of death. We extend frequentist‐based hypothesis tests previously developed for non‐informative coarsening and propose a novel Bayesian method based on comparing a posterior parameter ...

Musculoskeletal Symptomatic Areas After Total Knee Replacement for Osteoarthritis

ACR Open Rheumatology, 2019
Objective The objective of this study was to measure cumulative incidence and incidence rate and identify factors associated with new musculoskeletal (MSK) symptomatic areas after total knee replacement (TKR) for osteoarthritis (OA).

HIV incidence declines in a rural South African population: a G-imputation approach for inference

BMC Public Health, 2020
Background Ad hoc assumptions about the unobserved infection event, which is known only to occur between the latest-negative and earliest-positive test dates, can lead to biased HIV incidence rate estimates.
