Interactions in the 2×2×2 factorial randomised clinical STEPCARE trial and the potential effects on conclusions : a protocol for a simulation study
Background: Randomised clinical trials with a factorial design may assess the effects of multiple interventions in the same population. Factorial trials are carried out under the assumption that the trial interventions have no interactions on outcomes. Here, we present a protocol for a simulation study investigating the consequences of different levels of interactions between the trial interventio
