Soft Tissue Descent of Pelvic Structures With Straining, Comparing African-American and White Participants

	Race
	African American (n=56)		White (n=178)		P
	Abnormal Descent [n (%)]	Mean±SD Descent^†	Abnormal Descent [n (%)]	Mean±SD Descent^†	Abnormal Descent^*	Mean Descent^†
Distance from bladder neck to pubococcygeal line	24 (44.4)	1.1±0.6	74 (41.8)	0.9±0.6	.76	.17^‡

All dimensions are in centimeters unless otherwise noted.

P value for ϰ² test (controlling for cohort).

^†

Mean descent was quantified only for those with abnormal descent. P value for analysis of variance (controlling for cohort).

^‡

Adjusted for significant interaction for cohort and race (P value for interaction is .020).
