Our paper on applying missingness DAGs to longitudinal trial data has just been published in Biostatistics: academic.oup.com/biostatisti…
A challenging but rewarding experience.
We give ideas on useful rules of thumbs & how to explore deviations from the assumed missingness process.
Causal inference with missing data? Are missingness DAGs and graphical M(N)AR concepts, as proposed by @Carthica & @yudapearl, readily applicable to complex longitudinal studies? Check out our preprint led by @a_holovchak 👇

When selecting a causal estimand, it’s crucial to balance asking the right question with the feasibility of answering it under realistic assumptions. Ignoring this in clinical trials risks chasing shadows. arxiv.org/abs/2409.11162 1/2 #CausalInference #PharmaStats #Estimands

Win ratio has been widely used, but so far with little attention to its estimand. I argue for articulating the estimand as a first step to analysis, and explain how👇

Finally the debate is settled...., or not.
Our (with @Frank_Bretz and Oliver Dukes) review article on covariate adjustment for marginal treatment effects is now published in Clinical Trials: doi.org/10.1177/174077452412…; along with a commentary by @f2harrell : doi.org/10.1177/174077452412… and our rejoinder: doi.org/10.1177/174077452412….
