  1. aNumber of responders for whom that dimension at that recall period was applicable. Regarding the total scores, if responders skipped one of the recall periods, the total score for that dimension was not calculated
  2. The scores were calculated on a scale from 0-100; a higher score means a greater impact of endometriosis on that dimension of life. 0=Minimum impact of endometriosis as measured by the EIQ; 100= maximum possible impact of endometriosis as measured by the EIQ
  3. Out of 423 responders, 26 (6.1%) participants skipped items from the sexual dimension, 26 (6.1%) participants skipped items from the employment dimension, 152 (35.9%) participants skipped items from the education dimension, and 8 (1.9%) participants skipped items from the fertility and lifestyle dimensions
