NITPicker: selecting time points for follow-up experiments [PDF]
Background The design of an experiment influences both what a researcher can measure, as well as how much confidence can be placed in the results. As such, it is vitally important that experimental design decisions do not systematically bias research ...

Deterministic linkage for improving follow-up time in a Brazilian population-based cancer registry [PDF]
Population-based cancer registries (PBCR) are the primary source of cancer incidence and survival statistics. The loss to follow-up of these patients is concerning since it reduces the reliability of any statistical analysis.

Measuring follow-up time in routinely-collected health datasets: Challenges and solutions. [PDF]
A key requirement for longitudinal studies using routinely-collected health data is to be able to measure what individuals are present in the datasets used, and over what time period.

Longitudinal clinical trials with adaptive choice of follow-up time. [PDF]
Summary In longitudinal studies comparing two treatments with a maximum follow-up time there may be interest in examining treatment effects for intermediate follow-up times. One motivation may be to identify the time period with greatest treatment difference when there is a non-monotone treatment effect over time; another motivation may ...

Two-stage optimal designs with survival endpoint when the follow-up time is restricted [PDF]
Background Survival endpoint is frequently used in early phase clinical trials as the primary endpoint to assess the activity of a new treatment. Existing two-stage optimal designs with survival endpoint either over estimate the sample size or compute ...
