The mean±SD age of the participants was 34.44±7.27, 34.59±6.8 and 36.47±7.4 years in the 1st, 2nd, and 3rd tertile, respectively. The demographic characteristics of the subjects are presented in Table 1.
The distribution of the DIP score between tertiles is shown in Table 2. Large differences in DIP scores were observed for fat (P-value:0.04), riboflavin (P-value<0.001), folic acid (P-value<0.001), cobalamin (P-value=0.005), ascorbic acid (P-value<0.001), vitamin A (P-value<0.001), beta carotene (P-value<0.001), zinc (P-value<0.001), tea (P-value=0.002), magnesium (P-value<0.001), onion (P-value<0.001), fiber (P-value<0.001), caffeine (P-value=0.03), SAFA (P-value=0.02), and cholesterol (P-value<0.01) between the tertiles.
The mean±SD plasma levels of endothelial markers in different tertiles are shown in Table 3. There was no significant association between DIP and E-selectin in the crude model (P-value= 0.35) compared to model I (P-value= 0.57), model II (P-value= 0.57) and model III (P-value= 0.67) after adjusting for potential confounders (Figure 1).
The results showed no significant association between DIP and the plasma level of sICAM-1 in the crude model (P-value: 0.83) compared to model I (P-value: 0.98), model II (P-value: 0.98) and model III (P-value: 0.92) after adjusting for potential confounders (Figure 2).
In addition, no significant association was found between DIP and the plasma level of sVCAM-1 in the crude model compared to model I (P-value: 0.49), model II (P-value: 0.45) and model III (P-value: 0.50) after adjusting for potential confounders (Figure 3).
