ROC curves demonstrating the cumulative relative frequencies of EST before and after EA in a) women, n = 22, EST ranging from 1 to 7, and in b) men, n = 21, EST ranging from 1 to 8. From the ROC curve in Figure 3a it appears that the EST was assessed 4 in 86% of the women before EA and in 77% of the 22 women after EA. It is also obvious that the median EST was 3 (50% of the 22 women) both before and after EA. The ROC is nearly close to the main diagonal indicating that there was no systematic change among the women in the assessed EST before compared to after EA. The ROC curve in Figure 3b indicates systematic change both in position and concentration in assessed EST among the men.
