Primary Outcome Measures

Name	Time	Method
Quality of Life Questionnaire	Week 12	Physical and mental QOL components will be measured with the Endometriosis Health Profile Questionnaire. Scores range from 0 to 100, higher scores reflect more symptoms and worse health status.
Pain Measurement	Week 12	Pain will be measured with components of the EPHect participant questionnaire using the mean number of analgesic and/or opioid pills taken per week.
Quality of Life Survey	Week 12	Physical and mental QOL components will be measured with the Short Form-12 survey. There are two components, a physical component summary (PCS) and a mental health component summary (MCS). Both have a range of 0 to 100, higher scores represent better health.
Tumor Necrosis Factor Measurement	Week 12	Measurement of circulating levels of soluble tumor necrosis factor (TNF) alpha-receptor 1.
Inflammatory Markers	Week 8	Measurement of circulating levels of inflammatory markers (interleukin (IL)-6 and IL-1β.
Protein Measurement	Week 12	Measurement of circulating levels of high sensitivity-C-reactive protein.
Tumor Necrosis Factor Measurement #2	Week 12	Measurement of circulating levels of soluble TNF alpha-receptor 2.
inflammatory Markers	Week 12	Measurement of circulating levels of inflammatory markers (interleukin (IL)-6 and IL-1β.

Secondary Outcome Measures

Name	Time	Method
Qualify of Life Questionnaire	6 months	Physical and mental QOL components will be measured with the Endometriosis Health Profile Questionnaire. Scores range from 0 to 100, higher scores reflect more symptoms and worse health status.
Pain Measurement	12 months	Pain will be measured with components of the EPHect participant questionnaire using the VAS pain score. Scores range from 0 to 10, higher score is more pain (worse).
Quality of Life Questionnaire	12 months	Physical and mental QOL components will be measured with the Endometriosis Health Profile Questionnaire. Scores range from 0 to 100, higher scores reflect more symptoms and worse health status.
