The remaining seven indicators identified as credible candidates included age (0.026, 1.003–1.054), tumor diameter (1.281, 1.091–1.504), surgical method (2.088, 1.098 to −3.968), and CK7 (0.356, 0.167–0.760), Ki-67 (2.672, 1.535–4.650), PTEN (1.960, 1.130–3.400), and mTOR (0.483, 0.256–0.909) expression (Table 4).
