Associations of usual alcohol consumption and risk of stroke

Adjusted for age, smoking, and history of diabetes, and stratified by sex and EPIC center. Baseline alcohol consumption categories amongst current drinkers were >0 to ≤50 grams/week, >50 to ≤100 grams/week, >100 to ≤150 grams/week, >150 to ≤250 grams/week, >250 to ≤350 grams/week and >350 grams/week. The reference category is the lowest baseline alcohol consumption category (>0 and ≤50 grams/week). HRs are plotted against the mean usual alcohol consumption in each category. Studies with fewer than 5 events of any outcome were excluded from the analysis of that outcome. The sizes of the boxes are proportional to the inverse of the variance of the log-transformed HRs. Vertical lines represent 95% CIs.
