Fig 2. Overall survival curves according to the metabolic phenotypes of pancreatic cancer, including glucose-dependent metabolism (a), glutamine-dependent metabolism (b), combination of the two metabolism categories including glucose- and glutamine-dependent metabolism (c), and numbers of metabolism subtypes (d).

We assumed that mixed types composed of two main types within glucose- and glutamine-dependent metabolism (i.e. Warburg effect and Reverse Warburg effect, Canonical type and Non-canonical type), and the null types were not composed of any of the two main types in glucose- and glutamine-dependent metabolism (i.e. neither Warburg effect nor Reverse Warburg effect, neither Canonical type nor Non-canonical type.
