Hello again. Long time no see ;-)

I had to look up ‘crossover study’ (on Wikipedia) and inform myself of the need for a crossover trial, its benefits and disadvantages. This study (of yours) must be really important to invest time (getting participants agreements, collecting data, and using a not-free statistical analysis package) and worth posting. But I found no information on the ‘study’, the reason for using crossover trial or any ‘learning’ from this trial (do we have to wait for the ‘publication’ –some 12 months to go?). I think promoting a commercial tool is not a role of researchers.
