Mediation and spillover effects in group-randomized trials: a case study of the 4Rs educational intervention

Educational trials

VanderWeele TJ, Hong G, Jones SM.
GSID: eXEVyqfs75cJ
TJ VanderWeele, G Hong, SM Jones… - Journal of the American …, 2013 - Taylor & Francis

Peer influence and social interactions can give rise to spillover effects in which the exposure of one individual may affect outcomes of other individuals. Even if the intervention under study occurs at the group or cluster level as in...

On the definition of a confounder.

Annals of statistics

VanderWeele TJ, Shpitser I.
PMID: 25544784
Ann Stat. 2013 Feb;41(1):196-220. doi: 10.1214/12-aos1058.

The causal inference literature has provided a clear formal definition of confounding expressed in terms of counterfactual independence. The causal inference literature has not, however, produced a clear formal definition of a confounder, as it has given priority to...

Sensitivity analysis for direct and indirect effects in the presence of exposure-induced mediator-outcome confounders.

Epidemiology, biostatistics and public health

VanderWeele TJ, Chiba Y.
PMID: 25580387
Epidemiol Biostat Public Health. 2014;11(2). doi: 10.2427/9027.

Questions of mediation are often of interest in reasoning about mechanisms, and methods have been developed to address these questions. However, these methods make strong assumptions about the absence of confounding. Even if exposure is randomized, there may be...

Sensitivity analysis for contagion effects in social networks.

Sociological methods & research

VanderWeele TJ.
PMID: 25580037
Sociol Methods Res. 2011 May;40(2):240-255. doi: 10.1177/0049124111404821.

Analyses of social network data have suggested that obesity, smoking, happiness and loneliness all travel through social networks. Individuals exert "contagion effects" on one another through social ties and association. These analyses have come under critique because of the...

Sustained Complete Response to Cytotoxic Therapy and the PARP Inhibitor Veliparib in Metastatic Castration-Resistant Prostate Cancer - A Case Report.

Frontiers in oncology

VanderWeele DJ, Paner GP, Fleming GF, Szmulewitz RZ.
PMID: 26258074
Front Oncol. 2015 Jul 22;5:169. doi: 10.3389/fonc.2015.00169. eCollection 2015.

Solid tumors harboring BRCA1 or BRCA2 mutations have been shown to respond to PARP inhibitors. These responses are partial and transient. In this case report, we describe an 82-year-old male with poorly differentiated prostate cancer with metastases to the...

Sharp sensitivity bounds for mediation under unmeasured mediator-outcome confounding.

Biometrika

Ding P, Vanderweele TJ.
PMID: 27279672
Biometrika. 2016 Jun;103(2):483-490. doi: 10.1093/biomet/asw012. Epub 2016 Apr 30.

It is often of interest to decompose the total effect of an exposure into a component that acts on the outcome through some mediator and a component that acts independently through other pathways. Said another way, we are interested...

Directed acyclic graphs with edge-specific bounds.

Biometrika

Vanderweele TJ, Tan Z.
PMID: 23049135
Biometrika. 2012 Mar;99(1):115-126. doi: 10.1093/biomet/asr059. Epub 2011 Dec 20.

We give a definition of a bounded edge within the causal directed acyclic graph framework. A bounded edge generalizes the notion of a signed edge and is defined in terms of bounds on a ratio of survivor probabilities. We...

SOME DESIRABLE PROPERTIES OF THE BONFERRONI CORRECTION: IS THE BONFERRONI CORRECTION REALLY SO BAD?.

Effect partitioning under interference in two-stage randomized vaccine trials.

Statistics & probability letters

Vanderweele TJ, Tchetgen Tchetgen EJ.
PMID: 21532912
Stat Probab Lett. 2011 Jul 01;81(7):861-869. doi: 10.1016/j.spl.2011.02.019.

In the presence of interference, the exposure of one individual may affect the outcomes of others. We provide new effect partitioning results under interferences that express the overall effect as a sum of (i) the indirect (or spillover) effect...

Can post-neoadjuvant therapy molecular classification guide future treatment selection for muscle-invasive bladder cancer?.

How to report E-values for meta-analyses: Recommended improvements and additions to the new GRADE approach.

Environment international

Mathur MB, VanderWeele TJ.
PMID: 34954645
Environ Int. 2021 Dec 24;160:107032. doi: 10.1016/j.envint.2021.107032. Epub 2021 Dec 24.

In a recent concept paper (Verbeek et al., 2021), the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group provides a preliminary proposal to improve its existing guidelines for assessing sensitivity to uncontrolled confounding in meta-analyses of nonrandomized...
