CTML Visiting Student Researcher alum Carlos Garcia Meixide and CTML co-director Mark van der Laan present a new approach to causal inference. The new paper challenges the traditional assumption-based identification to what can be learned directly from observed data using implied interventions. By leveraging instrumental variable structure and Highly Adaptive Lasso (Hal), the authors propose a transparent G-computation formula that identifies causal effects without needing to specify everything up front.

CTML Faculty Laura Balzer was honored to present her talk, “Machine Learning in Randomized Trials? We Can & We Should!” at the Statistical Issues in Clinical Trials conference, hosted by the University of Pennsylvania on April 7th.
This annual conference addresses active areas of biostatistical research, including important conversations on how to effectively and validly implement covariate adjustment to improve statistical power in randomized trials. Speakers covered topics of broad relevance—such as covariate adjustment in group-sequential and re-randomization designs, complexities of adjustment in the face of missing covariate data, machine learning for covariate selection, and the role of covariate adjustment in the drug and device approval process.

Post image A growing body of epidemiologic research is examining the health effects of social policies. In this area, researchers face multiple challenges to causal inference, because policies are nuanced and rarely randomized, effects are often imprecisely estimated, and distinct subsets of population are affected differently. In this talk, I will discuss a framework for thinking about these challenges, and address two of them in depth: heterogeneity in the effects of policies across population subgroups and treatment-confounder feedback. For each challenge, I will describe the problem, characterize its magnitude, and discuss practical solutions.

Join us next week for another exciting talk in our CTML Seminar Series!

Survival is a key metric for evaluating current standards of care for individuals living with HIV. In resource-limited settings, high rates of loss to follow-up (LTFU) often result in underestimation of mortality when only observed deaths are considered. Resampling, which tracks a subset of LTFU patients to ascertain their outcomes, mitigates bias and improves survival estimates. However, common estimators for survival in resampling designs—such as weighted Kaplan-Meier (KM)—fail to leverage covariate information collected during repeated clinic visits, even though this information is highly predictive of survival.

We propose a novel Targeted Maximum Likelihood Estimator (TMLE) for survival in resampling designs, which addresses these limitations by leveraging baseline and longitudinal covariates to achieve greater efficiency. We present: (1) a fully efficient TMLE for data from resampling studies with fixed follow-up time for all participants and (2) an inverse probability of censoring weighted (IPCW) TMLE that accounts for varied follow-up times by stratifying on patients with sufficient follow-up to evaluate survival. This IPCW-TMLE can be made highly efficient through nonparametric or targeted estimation of the follow-up censoring mechanism.

The Riesz representation theorem allows us to express any target parameter as an inner product of a conditional mean and the Riesz representer, sparking new causal inference work to directly estimate the Riesz representer instead of solving for its analytical form. Causal neural networks are a popular choice for double machine learning Riesz regression estimators because they are universal function approximators. However, existing structures poorly estimate the Riesz representer and are susceptible to under-coverage or variance blow up under positivity violations. We propose RieszDragon, a neural network architecture combining Riesz-based regression weighting and collaborative, stratified potential outcome modeling to improve MSE and coverage in finite samples.
