Vine copula knockoffs for variable selection in gene expression studies

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Identifying clinical and genetic markers is essential for stratifying cancer patients by survival outcomes and guiding personalized treatment strategies. However, gene expression studies often involve high‐dimensional predictors with mixed data types and complex dependence, which complicates reliable variable selection.

Nonparametric maximum likelihood estimation of the survival function using current lifetime data

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract An issue when estimating the failure time survival function is how to set up a prevalent cohort study infrastructure to follow subjects after enrollment. This problem can be circumvented through the well‐known Grenander density estimator using current lifetime observations only.

Z‐residuals diagnostics for Cox models: Functional‐form misspecification versus nonproportional hazards

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Primary biliary cholangitis (PBC) is a progressive autoimmune cholestatic disease for which modelling death, with transplantation as a competing event, is clinically important. Cox proportional hazards (PH) models are widely used, but standard diagnostics detect lack of fit without distinguishing non‐PH from misspecified covariate functions ...

Siblings With Duchenne Muscular Dystrophy: Exploring Diagnosis Age and Disease Progression in a Genetic Therapy‐Naïve Cohort

open access: yesAnnals of the Child Neurology Society, EarlyView.
ABSTRACT Introduction Duchenne muscular dystrophy (DMD) is the most common pediatric muscular dystrophy. Typically, there is a ~ 2‐year delay between symptom onset and diagnosis. Limited data on outcomes in early‐diagnosed individuals have limited the understanding of the clinical impact of early diagnosis.

Genomic Insights Into Risperidone Treatment Outcomes in Children and Adolescents: Experience From a Psychiatric Hospital Serving Rural Youth

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Risperidone is a commonly used antipsychotic for treating psychiatric illness in children and adolescents. There is a large variability in risperidone response and discontinuation rates remain high. Pharmacogenomics offers the opportunity to improve risperidone outcomes, yet studies in pediatric populations are limited.

Non‐Invasive Estimation of Systemic Drug Exposure Using Exhaled Breath Metabolomics in Humans: A Translational Proof‐of‐Concept Study

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Accurate assessment of systemic drug exposure in humans remains challenging, as conventional approaches rely on intermittent blood sampling and laboratory‐based assays that are invasive and provide limited temporal resolution. Exhaled breath contains volatile and semi‐volatile compounds arising from drug metabolism and downstream biological processes ...
