In the subset of males, the effect of smoking was of borderline significance (t = 1.944, p = 0.052), but in the subset of the females the effect was considerable (t = 5.910, p < 0.0001).

Although a positive trend was visible, no statis- tical significance has been reached so far because of the limited number of tested subjects and the presence of three subjects with low spontaneous levels and high induc- ibility.
