  1. Italic values are statistically significant at P <0.05
  2. Vitamin C intake is presented as median (percentile 25th–percentile 75th) and other as mean (SD)
  3. P-value for analysis of co variance (ANCOVA) adjusted for confounding effects of age and gender
  4. P value of vitamins E and C based on Kruskal–Wallis and otherwise based on one way ANOVA
