Evaluating the Effectiveness of a Roblox Video Game (Super U Story) in Improving Body Image Among Children and Adolescents in the United States: Randomized Controlled Trial

The first metric of intervention gameplay was calculated through time stamps in the datafile, which was the difference between the last pre-exposure state measure completed and the first postexposure state measure completed. The second metric to assess intervention engagement was self-report questions at the end of the T2 questionnaire just before the acceptability questions.

Federated Analysis With Differential Privacy in Oncology Research: Longitudinal Observational Study Across Hospital Data Warehouses

Federated Analysis With Differential Privacy in Oncology Research: Longitudinal Observational Study Across Hospital Data Warehouses

In R, the main open-source library is the diffpriv library [13] that implements some DP mechanisms but not a real suite of functions ready to use, and which is not actively supported with last contributions going back to 2017. Furthermore, none of these tools were directly compatible with the Data SHIELD framework, which requires a specific interface in R. As a result, a new open-source a DP R package (R Core Team) for Data SHIELD has been implemented: ds Privacy.

Engagement With Digital Adherence Technologies as Measures of Intervention Fidelity Among Adults With Drug-Susceptible Tuberculosis and Health Care Providers: Descriptive Analysis Using Data From Cluster-Randomized Trials in Five Countries

The dataset used for the analysis was based on the last dose day recorded on November 15, 2022, and the data extract was dated December 7, 2022. A 3-week window was therefore allowed for any HCP activity, such as adding manual doses or overwriting data due to connectivity issues, to occur. Descriptive analysis was used to provide an overview of dose-day outcomes.
