We identified 70 47 cases cancer among (9 follow-up 170,640 person-years) (7 284,948 person-years), respectively. used Cox proportional hazards regression estimate relative (RR) 95% confidence interval (CI) incidence. After adjustment for potential confounders, RR (95% CI) drinking never, occasionally more cups/day were 1.00 (Reference), 0.71 (0.46-1.09) 0.58 (0.36-0.96), respectively (p trend = 0.024). In subgroup disease, found significant inverse Our findings support hypothesis decreases Further investigate role prevention high-risk population are needed.
