Associations of usual dairy intake (g/day) with the incidence of total cancer, liver cancer, lymphoma and female breast cancer. Cox regression analyses were performed among 510,146 participants with no prior self-reported history of cancer at baseline. Analyses were stratified by age-at-risk (continuous), sex (dichotomous variable) and region (ten regions) and were adjusted for education (four categories), income (four categories), smoking (four categories), alcohol consumption (four categories), total physical activity (continuous variable), family history of cancer (dichotomous), fresh fruit consumption (five categories), soy consumption (three categories) and BMI (continuous variable). B Analysis for liver cancer was additionally adjusted for HBsAg status (three categories). The y axis was plotted on a loge scale with the lowest intake group (never/rarely) as a reference category. The estimated crude mean values of usual dairy intake (g/day) were 24.0, 44.4 and 80.8 g/day in the lowest (never/rarely), medium (monthly) and highest (regular) intake groups, respectively. The FDR-corrected P trend values for the associations with incidence of total cancer, liver cancer, lymphoma and female breast cancer were 0.002, 0.04, 0.17 and 0.01, respectively. The black squares represent HRs with the size being inversely proportional to the variance of the loge of HR and the vertical lines represent 95% CIs. The numbers above the vertical lines are point estimates for HRs and the numbers below the lines refer to the number of incident cancer cases. Dashed diagonal lines indicate the linear associations between dairy intake and cancer risk
