  • a Geometric mean levels with SEs are shown.

  • b Mean age (SDs) was 69.1 (7.7) in African-Americans, 69.8 (7.8) in whites, and 70.4 (6.8) in Asian-Americans. The range in age was 40–84 in African-Americans, 35–89 in whites, and 47–85 in Asian-Americans.

  • c Adjusted for age (in single years).

  • d Two-sided P for trend.
