Power analysis for stepped wedge trials with multiple interventions
Sign Up to like & getrecommendations! Published in 2022 at "Statistics in Medicine"
DOI: 10.1002/sim.9301
Abstract: Stepped wedge design (SWD) trials are cluster randomized trials that feature staggered, unidirectional crossâover between treatment conditions. Existing literature on power for SWDs focuses primarily on designs with two conditions, typically a control and an… read more here.

DOI: 10.1016/j.petrol.2018.08.068
Abstract: Abstract An all too often question when designing field trials aimed at the validation of EOR techniques is how long the stimulation should last. In these trials, the stimulation period is proportional to the trial… read more here.

DOI: 10.1037/met0000330
Abstract: This article proposes a summary-statistics-based power analysis-a practical method for conducting power analysis for mixed-effects modeling with two-level nested data (for both binary and continuous predictors), complementing the existing formula-based and simulation-based methods. The proposed… read more here.

DOI: 10.1038/s41437-019-0205-3
Abstract: Power calculation prior to a genetic experiment can help investigators choose the optimal sample size to detect a quantitative trait locus (QTL). Without the guidance of power analysis, an experiment may be underpowered or overpowered.… read more here.
