Mean carotid intima-media thickness (IMT) with upper limit of 95% confidence interval in FOOD ADDITIVE PHOSPHATE (FAP) intake groups for ALL SUBJECTS (WHITE SCALE; 1: n = 66; 2: n = 111, 3: n = 151; 4: n = 109, 5: n = 85; 6: n = 29; p for all 0.097, ANCOVA), for FEMALES (GRAY SCALE; 1: n = 45; 2: n = 77; 3: n = 101; 4: n = 73; 5: n = 55; 6: n = 20; p for all 0.267, ANCOVA), and for MALES (BLACK SCALE; 1: n = 16; 2: n = 39; 3: n = 54; 4: n = 28; 5: n = 33; 6: n = 10; p for all 0.372, 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 FAP intake group (ANCOVA) / statistically significant trends (contrast analysis) between FAP intake and IMT are indicated with asterisks (*p < .05, **p < 0.01) (between all other groups p > 0.05).
