Known Groups Analyses Examining EPBD Discriminating Ability: Mild versus Severe Symptom Groups

Average Daily EPBD Pain Rating	Mild Symptoms Mean (SD)	Severe Symptoms Mean (SD)	t
Pelvic Pain - Intermittent	1.21 (1.4), n = 60	2.00 (1.8), n = 68	-2.70*
Pelvic Pain - Continuous	0.89 (1.3), n = 60	2.06 (2.1), n = 68	-3.80†
Dysmenorrhea - Intermittent	1.76 (1.6), n = 58	3.19 (2.2), n = 66	-4.13‡
Dysmenorrhea - Continuous	2.40 (2.0), n = 58	3.90 (2.5), n = 66	-3.70†
Dyspareunia	1.69 (1.9), n = 49	2.68 (2.4), n = 53	-2.29
Pain Interference	0.85 (1.0), n = 60	1.91 (1.8), n = 68	-4.16†

EPBD = Endometriosis Pain and Bleeding Diary; SD = standard deviation.
