Thanks to the greater statistical power a repeated measures design can use fewer subjects to detect a desired effect size. In practice it is not necessary that all permutations of all treatments be used. The increased precision often translates into a smaller sample size.

Several advantages and disadvantages are worth considering when looking at cross-sectional studies. Crossover and self-controlled designs in clinical research. 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. The AdvAntAges of using A crossover design 21 each subjecT serves as hisher own conTrol In general each subject in a crossover study receive all intervention at least once. However crossover studies can take longer to complete since patients will receive multiple treatments during the trial. Crossover trials produce within participant comparisons whereas parallel.
