aAge of patients when diagnosed with gastric cancer.
bDiagnosis interval between gastric cancer and primary gastric lymphoma of each case is presented as an estimated whole year. The diagnosis of gastric cancer earlier than gastric lymphoma is indicated by a negative number, and the diagnosis of gastric cancer later than gastric lymphoma is indicated by a positive number.
