Mean carotid intima-media thickness (IMT) with upper limit of 95% confidence interval in TOTAL PHOSPHORUS (TP) intake quintiles for ALL SUBJECTS (WHITE SCALE; 1st: 0–1272 mg/d, n = 109; 2nd: 1273–1462 mg/d, n = 109; 3rd: 1463–1665 mg/d, n = 109; 4th: 1666–1962 mg/d, n = 109; 5th: 1963–3205 mg/d, n = 110; p for all 0.233, ANCOVA), for FEMALES (GRAY SCALE; 1st: 0–1232.7 mg/d, n = 74; 2nd: 1233–1390 mg/d, n = 74; 3rd: 1391–1563 mg/d, n = 75; 4th: 1564–1795 mg/d, n = 73; 5th: 1796–2800 mg/d, n = 74; p for all 0.293, ANCOVA) and for MALES (BLACK SCALE; 1st: 0–1443 mg/d, n = 34; 2nd: 1444–1610 mg/d, n = 35; 3rd: 1611–1850 mg/d, n = 35; 4th: 1851–2163.9 mg/d, n = 36; 5th: 2164.0-3205 mg/d, n = 35; p for all 0.719, ANCOVA). The data are adjusted for sex (when analyzing all subjects), age, LDL-HDL cholesterol ratio, smoking status, and IMT sonographer class. Statistically significant differences from the highest TP intake quintile (ANCOVA) are shown with an asterisk (* p < 0.05) (between all other groups p > 0.05).
