Sample size and power calculations for open cohort longitudinal cluster randomized trials.
Kasza, J; Hooper, R; Copas, A; Forbes, AB (John Wiley and Sons, 2020-03-04)When calculating sample size or power for stepped wedge or other types of longitudinal cluster randomized trials, it is critical that the planned sampling structure be accurately specified. One common assumption is that ... -
The staircase cluster randomised trial design: A pragmatic alternative to the stepped wedge.
Grantham, KL; Forbes, AB; Hooper, R; Kasza, J (2023-11-30)This article introduces the 'staircase' design, derived from the zigzag pattern of steps along the diagonal of a stepped wedge design schematic where clusters switch from control to intervention conditions. Unlike a complete ... -
A tutorial on sample size calculation for multiple-period cluster randomized parallel, cross-over and stepped-wedge trials using the Shiny CRT Calculator.
Hemming, K; Kasza, J; Hooper, R; Forbes, A; Taljaard, M (2020-06-01)It has long been recognized that sample size calculations for cluster randomized trials require consideration of the correlation between multiple observations within the same cluster. When measurements are taken at anything ...
