Privacy-Preserving Causal Meta-Mediation Analysis with Survival Outcomes
Marie-Félicia Beclin, Tat-Thang Vo
Privacy and data-governance constraints often prevent pooling individual-level data across studies, limiting the use of conventional approaches for causal media- tion analysis in m…
Causally Interpretable Meta-Mediation Analysis With Missing At Random Mediator and Outcome Data
Marie-Félicia Beclin, Apolline Courrèges-Vartanian, Geneviève Lefebvre +1
Meta-analyzing natural indirect effect estimates from multiple studies is increas- ingly used to synthesize evidence on causal pathways of interest. However, stan- dard mediation m…
A linear regression model for quantile function data applied to paired pulmonary 3d CT scans
Marie-Félicia Béclin, Pierre Lafaye de Micheaux, Nicolas Molinari +1
This paper introduces a new objective measure for assessing treatment response in asthmatic patients using computed tomography (CT) imaging data. For each patient, CT scans were ob…
Transportability of aggregate trial results to an external environment in causally interpretable meta-analysis
Tran Trong Khoi Le, Marie-Felicia Béclin, Sivem Afach +1
In evidence synthesis, multilevel modeling approaches (MMAs) are commonly employed to combine aggregate data (AD) and individual participant data (IPD). These approaches rely on an…
