Figure 1.
Causal pies and causal-pie weights for a hypothetical example.
Four possible classes of causal pies for two hypothetical binary risk factors, A and B, in disease causation. The numbers shown below the pies are the causal-pie weights.

Causal-pie weights and the bootstrapped 95% confidence intervals for newly-developed hepatocellular carcinoma.
A total of eight classes of causal pies (U: unmeasured factors) are presented. The eight pies are grouped into three intersecting sets (the dotted circles).
