Dear God, that [0] link is horrendous. I might be biased because I come from a harder science, but every metric they measure overlap in the stddev within the control and the test group. The best is peak expiratory flow (ie., peak breath flow), but even those overlap from the min of one to the max of the other. I probably doesn't help that there are 25 subjects per group.
