Key clinical point: At least 13% of cases of multiple sclerosis (MS) can be prevented if tobacco smoking is avoided, indicating the need for integrated programs aimed not only at smoking cessation but also at smoking prevention.
Major finding: The overall attributable fraction (AF) of MS because of smoking was 13.1% (95% CI 10.7%-15.4%), with AF being 0.6% (95% CI 0%-2%) in ex-smokers, indicating the beneficial effects of smoking cessation. Ever-smokers were at a 41% (95% CI 1.33%-1.50%) increased risk for MS than never smokers.
Study details: This was a population-based matched case-control study including 9,419 patients with MS and 9,419 matched control individuals.
Disclosures: No external funding was received for this study. The authors declared no conflicts of interest.
