“…Cohorts were well balanced in terms of the sex ratio in only four studies (CS 14,25,33,37) [46,49,64,69]. In other cases, patients were from only one sex, usually only male (CS 1, 6,12,16,19,21,24,26,27,28,29,30,32,35,36) but sometimes only female (CS 18,20,22,23,34) [47,52,59,61,71], or largely imbalanced. Men are over-represented in cohorts of herbal clinical studies in the last 10 years where women are known to be under-represented [79].…”
