Prevalence of MS across apoB/apoA-I ratio tertiles among European-Americans and African-Americans. The cut-off points for tertiles were ≤0.98, 0.98–1.26, ≥1.26 for European-Americans and ≤0.88, 0.88–1.20, ≥1.20 for African-Americans, respectively. The results are based on n=99 for 1st, n=103 for 2nd and n=100 for 3rd tertiles in European-Americans and n=76 for 1st, n=74 for 2nd and n=74 for 3rd tertiles in African-Americans. Two European-American subjects (1 with and 1 without MS) were excluded from the analyses due to missing data.
