Text: Median plasma vitamin levels were increased in the treatment group between baseline and 1 year after randomization from 0. 43 micromol/L (interquartile range [IQR] = 0. 26-0. 69) to 2. 89 micromol/L (IQR = 1. 76-4. 22) for beta-carotene, from 26. 7 micromol/L (IQR = 23. 1-31. 2) to 54. 9 micromol/L (IQR = 42. 8-67. 6) for alpha-tocopherol, and from 47. 70 micromol/L (IQR = 36. 9-58. 5) to 61. 9 micromol/L (IQR = 52. 2-72. 7) for vitamin C. Overall progression rates per 100 person-years were 74. 3 in the placebo group and 67. 8 in the group randomly assigned to vitamins.
