Of course SUVs provide all those things too. Crossover studies clinical trials in which each patient receives two or more treatments in sequence and self-controlled studies in which each patient serves as his or her own control can produce results that are statistically and clinically valid with far fewer patients than would. Crossover design is only suitable for a condition that is stable when intervention effects are short-lived and do not cure the condition. Jeff gave his permission to use his software here and it was used to generate many of these graphs and suggested I promote the use of his response modeling software in addition to the crossover.
The advantages of the cross-over design are that each subject acts as his or her own control and that a smaller number of patients are required in comparison to parallel-group studies.
