  1. Significant values are in bold
  2. CSI—Cholesterol to saturated fat index; T—tertile
  3. *Calculated by analysis of variance (ANOVA)
  4. P valueb: ANCOVA was performed to adjust the potential confounding factor (energy intake)
  5. Data are mean ± SD
  6. P < 0.05 was considered significant
