A major challenge in the prospective trial design was achieving statistically meaningful results in a relatively small patient population. The crossover design created statistically and clinically valid results with fewer patients than would have been necessary for a parallel research design.17 The number of sufferers who completed both treatment periods and thus could be evaluated provided sufficient power to reach statistical significance . The use of a crossover design in a little study population also helps to prevent overestimation of the benefit of the therapy being tested,18 rendering it likely that our outcomes reflect a conservative evaluation of the benefits of AICC prophylaxis.
