    Abstract

    Six-year post-intervention follow-up of the CARET randomized trial.

    Key Findings

    Excess lung cancer risk in the supplement arm diminished after supplementation stopped, though risks remained elevated among women.

    Conclusions

    The harm from beta carotene appears largely reversible after discontinuation.

    Limitations

    Post-intervention observational follow-up; no continuing randomized comparison.

    Supplements Studied

    Excess lung cancer risk in the supplement arm diminished after supplementation stopped, though risks remained elevated among women.
