Figure 2. Evidence maturity across surgical decision nodes in pancreatic cancer. We classified each of the 31 direct AI studies at the highest cumulative evidence level for which it met all required criteria. The three adjacent studies or protocols were not graded. Supplementary Table 2 lists individual assignments and the evidence supporting them. Circle areas represent study counts, which are also shown numerically inside the circles.
