Regression output for all case groups was defined relative to the white race (control group). Patient factors previously demonstrating significant differences between the specific racial or ethnic group and white race (Table 1) were controlled for in the regression analyses.

Significant P-values (P < .05) are bolded.

^aValues represent correlation coefficients from a multivariate linear regression.
