CPP chronic pelvic pain. Bold numbers indicate statistical significance (p ≤ 0.05)
aFailure in permanent pain reduction was assumed if individual improvement of NRS Score at time of interview was lower than 20 points compared to pre-operative value. Median time between surgery and interview was 6 years (range 4.3–7.8). Only patients with a pre-operative NRS Score of > 20 were included
bPatients who answered “no” when questioned “Do you think your quality of life has improved after surgery?”, GC subjective general condition
cNo live birth after endometriosis surgery in patients with infertility before treatment
dNeed for repeated endometriosis surgery
gCombined oral contraceptives
hOral progestin or hormonal intrauterine device
*two patients were excluded who had bilateral adnexectomy and subsequent HRT with pure estradiol
