Testing for treatment effect twice using internal and external controls in clinical trials [PDF]

open access: yesJournal of Causal Inference, 2023
Leveraging external controls – relevant individual patient data under control from external trials or real-world data – has the potential to reduce the cost of randomized controlled trials (RCTs) while increasing the proportion of trial patients given ...

Role of placebo samples in observational studies [PDF]

open access: yesJournal of Causal Inference
In an observational study, it is common to leverage known null effects to detect bias. One such strategy is to set aside a placebo sample – a subset of data immune from the hypothesized cause-and-effect relationship. Existence of an effect in the placebo

Mediated probabilities of causation [PDF]

open access: yesJournal of Causal Inference
We propose a set of causal estimands that we call “the mediated probabilities of causation.” These estimands quantify the probabilities that an observed negative outcome was induced via a mediating pathway versus a direct pathway in a stylized setting ...

Generalized coarsened confounding for causal effects: a large-sample framework [PDF]

open access: yesJournal of Causal Inference
There has been widespread use of causal inference methods for the rigorous analysis of observational studies and to identify policy evaluations. In this article, we consider a class of generalized coarsened procedures for confounding.

Estimating average causal effects with incomplete exposure and confounders [PDF]

open access: yesJournal of Causal Inference
Standard methods for estimating average causal effects require complete observations of the exposure and confounders. In observational studies, however, missing data are ubiquitous. Motivated by a study on the effect of prescription opioids on mortality,

Simple yet sharp sensitivity analysis for unmeasured confounding

open access: yesJournal of Causal Inference, 2022
We present a method for assessing the sensitivity of the true causal effect to unmeasured confounding. The method requires the analyst to set two intuitive parameters. Otherwise, the method is assumption free. The method returns an interval that contains

Estimating marginal treatment effects under unobserved group heterogeneity

open access: yesJournal of Causal Inference, 2022
This article studies the treatment effect models in which individuals are classified into unobserved groups based on heterogeneous treatment rules. By using a finite mixture approach, we propose a marginal treatment effect (MTE) framework in which the ...

Conditional average treatment effect estimation with marginally constrained models

open access: yesJournal of Causal Inference, 2023
Treatment effect estimates are often available from randomized controlled trials as a single average treatment effect for a certain patient population.
