Microorganisms, 2023 Objectives: To explore the Cytomegalovirus (CMV) burden on the long-term post-transplant course in different donor ages, we evaluated the incidence and risk factors for CMV in our kidney-transplanted patients (KTs) with extensive adoption of expanded ...

Revisiting the cumulative incidence function with competing risks data
Journal of the Royal Statistical Society Series C: Applied Statistics, 2023 AbstractWe consider estimation of the cumulative incidence function (CIF) in the competing risks Cox model. We study three methods. Methods 1 and 2 are existing methods while method 3 is a newly proposed method. Method 3 is constructed so that the sum of the CIF’s across all event types at the last observed event time is guaranteed, assuming no ties ...

Modeling cumulative incidence function for competing risks data [PDF]
Expert Review of Clinical Pharmacology, 2008 A frequent occurrence in medical research is that a patient is subject to different causes of failure, where each cause is known as a competing risk. The cumulative incidence curve is a proper summary curve, showing the cumulative failure rates over time due to a particular cause. A common question in medical research is to assess the covariate effects

Summarizing differences in cumulative incidence functions
Statistics in Medicine, 2008 AbstractThe cumulative incidence function is widely reported in competing risks studies, with group differences assessed by an extension of the log‐rank test. However, simple, interpretable summaries of group differences are not available. An adaptation of the proportional hazards model to the cumulative incidence function is often employed, but the ...

Assessing cumulative incidence functions under the semiparametric additive risk model [PDF]
Statistics in Medicine, 2009 AbstractIn analyzing competing risks data, a quantity of considerable interest is the cumulative incidence function. Often, the effect of covariates on the cumulative incidence function is modeled via the proportional hazards model for the cause‐specific hazard function.

Cumulative Incidence Function in Studies on the Duration of the Unemployment Exit Process
Folia Oeconomica Stetinensia, 2017 When we analyse the employment seeking process, an event that ends the observation of a given individual is their employment. The remaining observations are considered to be censored: the observations concluded before the end of the study or the cases of

Archives of Endocrinology and Metabolism, 2021 Objective: Although some previous data have suggested a high iodine intake in Brazil, the prevalence of antithyroperoxidase antibodies (TPOAb) in the country is compatible with rates from countries with adequate iodine intake. This observation emphasizes
