a
Numbers of women with and without a diagnosis do not sum to the total (1,227) because 34 women have both diagnoses, and data on diagnosis of uterine leiomyomata are missing for three women.
b
Percentages for MEHHP and MEOHP are based on the 2001–2004 sample population (n = 838).
c
n = 838, 57, 113, and 689 for all women, women with endometriosis, women with uterine leiomyomata, and women with neither condition, respectively.
*
Significantly higher (p = 0.03) than among women with endometriosis or uterine leiomyomata.
