Distribution of Consistency of Care by Race and Wave
| Consistency of Care (n [%]) | Wave 1 (1987) (n = 2460) | Wave 2 (1990) (n = 2423) | Wave 3 (1994) (n = 1938) | Wave 4 (1998) (n = 1097) | P* | ||||
|---|---|---|---|---|---|---|---|---|---|
| African American (n = 1402) | White (n = 1058) | African American (n = 1385) | White (n = 1038) | African American (n = 1123) | White (n = 815) | African American (n = 624) | White (n = 473) | ||

* Two-sided test of racial difference in consistency of care characteristics over time using generalized estimating equations.
† Inconsistent care was not assessed at wave 1 because the definition requires data from 2 or more time periods.
