A hierarchical competing risks survival model in the study of child mortality in Bangladesh

Scientific Reports
Under-five child mortality remains a significant public health issue in Bangladesh and other developing countries. Identifying key risk factors within a hierarchical data structure is crucial for improving health system performance.

Cumulative incidence function estimation using population-based biobank data

Biometrics
ABSTRACT Many countries have established population-based biobanks, which are being used increasingly in epidemiological and clinical research. These biobanks offer opportunities for large-scale studies addressing questions beyond the scope of traditional clinical trials or cohort studies. However, using biobank data poses new challenges.

Methods of competing risks analysis of time to occurrence of reflux among children with antenatal hydronephrosis

Journal of Biostatistics and Epidemiology, 2016
Background & Aim: We aimed to describe a standard survival analysis, so that we can analyze some factors related to the time of occurrence of different types of reflux (unilateral-left, unilateralright, and bilateral) in children with antenatal ...

Opening the black box: defining true-negative outcomes in esophageal cancer screening — a population-based study

BMC Medicine
Background Current negativity definition in esophageal cancer screening overlooks the risk heterogeneity between individuals with non-dysplastic Lugol’s unstained lesions (ND-LULs) and normal-stained epithelium.

Identifiability and estimation of the sign of a covariate effect in the competing risks model. [PDF]

It is well known that the competing risks model is identified if the dependence structure between risks (the copula function) is known or assumed. Special cases include independence of risks or independent censoring.

Restricted estimation of the cumulative incidence functions corresponding to competing risks

, 2006
In the competing risks problem, an important role is played by the cumulative incidence function (CIF), whose value at time $t$ is the probability of failure by time $t$ from a particular type of failure in the presence of other risks. In some cases there are reasons to believe that the CIFs due to various types of failure are linearly ordered.
