In a prospective cohort study of 74 250 Swedish women and men, with 7.2 years of follow-up and 705 incident colorectal cancer cases, long duration of aspirin use (>20 years) was associated with a reduced risk of colorectal cancer (multivariate rate ratio: 0.65; 95% confidence interval: 0.45-0.94). Aspirin use for a shorter period was not associated with risk.
在一项针对74250名瑞典男性和女性的前瞻性队列研究中,随访7.2年,共出现705例结直肠癌病例,长期服用阿司匹林(>20年)与结直肠癌风险降低相关(多变量率比:0.65;95%置信区间:0.45 - 0.94)。较短时间服用阿司匹林与风险无关。
