Predicting Win‐Loss Probabilities for Composite Time‐to‐Event Outcomes Under The Proportional Win‐Fractions Regression Model

Statistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT For composite time‐to‐event outcomes, the win ratio as a relative measure ignores ties resulting from non‐occurrence of events, which can obscure important context in regression settings where event rates—and hence the proportion of ties—vary over time and across covariate values.

Proportional Hazards Regression for Interval‐Censored Outcomes With an Interval‐Censored Covariate

Statistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT Identifying predictors for viral rebound trajectories after antiretroviral therapy (ART) interruption is central to HIV cure research. Motivated by the need to determine whether the time to achieve viral suppression after ART initiation can predict the time to viral rebound following ART interruption, we investigate modeling approaches that ...

Joint Frailty Mixture Cure Model for Recurrent Event Data With Dependent Censoring: An MCEM Approach

Statistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT Advancements in modern medical technology have enabled cures for a fraction of patients while extending survival times for those who are not cured. For non‐cured patients, disease recurrence is influenced by observed covariates and unobserved individual heterogeneity (random effects).

Ossification of the cranium of Inpaichthys kerri (Characiformes: Acestrorhamphidae) with discussion of paedomorphic traits in the genus

Journal of Anatomy, Volume 248, Issue 5, Page 806-829, May 2026.
In this study, we present a detailed description of the cranial development of Inpaichthys kerri (Characiformes: Acestrorhamphidae), highlighting important topics such as pedomorphic characters and their relationship with ontogeny and phylogeny, as well as ossification sequences unique to the species. Abstract The study of development provides valuable

When Net‐Zero Goals Meet Zero‐Sum Realities: New Insights on the CSR‐Firm Value Effect and the Role of New Product Development Versus Marketing

Journal of Product Innovation Management, Volume 43, Issue 3, Page 516-538, May 2026.
ABSTRACT Academic Summary Corporate social responsibility (CSR) is a key strategy to achieving (e.g., environmental) sustainability. While many studies report a positive effect of CSR on firm value, growing evidence suggests practice often fails to unlock such effect.
