Outcome Measures

Primary Outcomes (3)

  • Visual analogue pain score(VAS)

    The visual analogue scale (VAS) was used to evaluate the pain. It is widely used in clinical practice in China. The basic method is to use a swimming ruler of about 10cm in length, marked with 10 scales on one side, and "0" and "10" points on both ends, with 0 points indicating no pain and 10 points indicating the most severe pain that can be endured.

    before drug treatment and 3 months after drug treatment

  • Endometriosis fertility index(EFI)

    EFI score of endometriosis refers to the evaluation of fertility in patients with normal semen in men and good ovarian reserve function in women without adenomyosis. The pregnancy rate was measured by quantifying the patient's age, the duration and type of infertility, and the function of the fallopian tubes, uterus, and ovaries. If the score is higher than 9, the patient can try natural pregnancy. If the score is 5-8 points, the patient can be monitored by fertility guidance, if not naturally pregnant, can be treated by IVF-ET. If the score is lower than 5 points, the patients can be directly treated by IVF-ET.

    before drug treatment and 3 months after drug treatment

  • The Cox Menstrual Symptom Scale(CMSS)

    The Cox menstrual symptom scale (CMSS) was used to evaluate the severity of symptoms and the duration of dysmenorrhea. The scale included 2 parts, CMSS-severity (CMSS-S) and CMSS-duration (CMSS-T), with a total of 18 observation indicators. It included 17 symptoms including nausea, vomiting, loss of appetite, headache, vertigo and the duration of dysmenorrhea. All CMSS-S items were scored on a 5-point scale: 0 as no symptoms, 1 as mild, 2 as moderate, 3 as severe, and 4 as extremely severe. CMSS-T is also a 5-point scale: 0 for no symptoms, 1 for persistent \< 3h, 2 for 3\~7h, 3 for 7\~24h, 4 for continuous \> 24 hours.
