Characterization of VWD cohorts

	Type 1 VWD cohort	Historical type 1 VWD cohort	Healthy control cohort
No. of subjects	310	172	257
No. Caucasian (%)	263 (85)	152 (88)	139 (54)
No. African American (%)	19 (6)	7 (4)	67 (26)
No. Hispanic (%)	35 (11)	16 (9)	46 (18)
No. female (%)	204 (66)	115 (67)	193 (75)
Mean (SD) age at enrollment	19 (15)	21 (16)	38 (11)

Subjects self categorized race (Caucasian, African American, Asian, American Indian, Native Hawaiian, and multiple race) and ethnicity (Hispanic and non-Hispanic), and had the option of not answering either question (>95% of each cohort had recorded answers for race and ethnicity). Race and ethnicity were separate questions and therefore the percentages do not always add up to 100%.
