- Design, analysis and presentation of factorial randomised controlled . . .
The evaluation of more than one intervention in the same randomised controlled trial can be achieved using a parallel group design However this requires increased sample size and can be inefficient, especially if there is also interest in considering combinations of the interventions An alternative may be a factorial trial, where for two interventions participants are allocated to receive

- Reporting of Factorial Randomized Trials - JAMA Network
In a factorial (or “at-the-margins”) analysis, all participants randomized to factor A (A alone and A plus B) are compared with all those not randomized to A (B alone and double-control) 2,4,6,11,35,36 Alternatively, in a multiarm (or “inside-the-table”) analysis, the trial is analyzed as if a multiarm design had been used 2,4-6,10-12,17,23,35,36 The 2 approaches offer different

- Factorial design: design, measures, and classic examples
While studies of factorial design are less prevalent than the classic randomized controlled trial (RCT), the factorial design offers many advantages including efficient evaluation of the main effects of many intervention components while maintaining adequate statistical power, and the ability to observe interactions between these components 1 Factorial design is an experiment with k factors
