Table 1.
Personal data of the 39 OCD patients.
Figure 1.
Sequences of functional acts (large circles) and non-functional acts (small circles).
Figure 2.
Frequency distribution of rituals according to the number of acts performed in the ‘tail’.
As shown, most control sequences did not have a tail or had a tail with 1–20 acts. In contrast, only few (9) of the 39 OCD sequences did not have a tail, whereas the others had a tail with numerous acts (median of 12 acts compared with a median of 2 acts in control sequences).
