Figure 6 Forest plot showing the association between dietary nut consumption and colorectal cancer risk. Squares and horizontal lines represent study-specific odds ratios (ORs) and 95% confidence intervals (CIs). The size of each square indicates the weighting of the study in the overall analysis depending on population size. Diamonds represent pooled ORs of all studies of that food item and 95%CI of the overall population. Vertical line indicates OR 1.0. CI: Confidence interval.
