Vaccination Coverage Against Coronavirus Disease 2019 (COVID‐19) in Brazil's Indigenous Population

open access: yesJournal of Medical Virology, Volume 98, Issue 5, May 2026.
ABSTRACT Indigenous populations in Brazil were prioritized for coronavirus disease 2019 (COVID‐19) vaccination due to their increased vulnerability. The aim of the study was to describe COVID‐19 vaccination coverage among Indigenous population across Brazilian regions and Special Indigenous Health Districts (DSEIs; acronym for Distritos Sanitários ...

How social norms are integrated in natural resource co‐management

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1050-1065, May 2026.
Abstract Social norms are increasingly recognized as central elements in fostering cooperation and compliance in natural resource co‐management, especially where communities and governments share authority. Yet, their conceptualization and application across disciplines remain fragmented.

A Unified Framework for Statistical Inference and Power Analysis of Single and Comparative Fβ$$ {F}_{\beta } $$ Scores

open access: yesStatistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT Machine learning and artificial intelligence are increasingly applied to medical diagnostics and clinical decision‐making. To evaluate model performance, the F1$$ {F}_1 $$ score and its generalized form, the Fβ$$ {F}_{\beta } $$ score, are widely used as they balance precision and sensitivity.

A Bayesian Causal Model for Matrix‐Valued Exposures With Applications to Radiotherapy Planning

open access: yesStatistics in Medicine, Volume 45, Issue 10-12, May 2026.
ABSTRACT In radiotherapy for cancer, organs surrounding the target tumor, known as organs‐at‐risk (OARs), should be protected from excessive radiation to avoid toxicity. Radiation exposure to multiple OARs can be summarized using matrix‐valued dose‐volume histograms (DVH), and understanding the causal relationship between DVHs and toxicity outcomes can

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

open access: yesStatistics 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.
