Why didn the clinical trials include a larger sample of people and why has it not been tested on women?
First of all, there is no statistical significance in a larger sample, so long as the sample is adequate and the protocol is truly random and blind. A few women were tested in the pilot studies, but we were not successful in convincing women to participate in a study that required tattooing the scalp, periodically cutting the hair in that area at scalp level and staying with this routine for 40 weeks. Because of the economics and effort required to convince a statistically significant sample (at least 21) to participate in such a study, we have tabled our test on women for the future.
