Days Alive at Home vs Out of Hospital: Why the Difference Matters for Trial Endpoints

Letao Yuan, Sarah N. Dawson, David S. Robertson +5

Days Alive and Out of Hospital (DAOH) and Days Alive at Home (DAH) are increasingly used as patient-centred primary outcomes in perioperative trials, and a recent editorial has adv…

Component over Composite: Mitigating Type I Error Inflation when Imputing "Days Alive and at Home"

Mia S. Tackney, Sarah Dawson, Letao Yuan +2

Background: Days Alive and at Home (DAH) over a pre-defined follow-up period is a novel post-intervention composite outcome that combines data from at least three components: (i) i…

Capturing the Curve: Functional Data Analysis for Validated Digital Outcome Measures

Mia S. Tackney, Marcos Matabuena, Marco Palma +7

Digital health technologies enable high-frequency collection of data in near-continuous time and capture rich information about the health of individuals. The raw data collected by…

Comparison of Parametric versus Machine-learning Multiple Imputation in Clinical Trials with Missing Continuous Outcomes

Mia S. Tackney, Jonathan W. Bartlett, Elizabeth Williamson +1

The use of flexible machine-learning (ML) models to generate imputations of missing data within the framework of Multiple Imputation (MI) has recently gained traction, particularly…

Multiple Imputation Approaches for Epoch-level Accelerometer data in Trials

Mia S. Tackney, Elizabeth Williamson, Derek G. Cook +3

Clinical trials that investigate interventions on physical activity often use accelerometers to measure step count at a very granular level, often in 5-second epochs. Participants…

Nonmyopic and pseudo-nonmyopic approaches to optimal sequential design in the presence of covariates

Mia S. Tackney, David C. Woods, Ilya Shpitser

In sequential experiments, subjects become available for the study over a period of time, and covariates are often measured at the time of arrival. We consider the setting where th…
