Prognostic impact and clinicopathological correlation of SLC6A13 expression in LIHC. (A–D) KM survival curves of OS, PFS, RFS, and DSS of SLC6A13. Red represents high expression and green represents low expression; (E–J) Analysis of the expression characteristics of SLC6A13 in patient’s gender, nodal metastasis status, tumor grade, individual cancer stages, Histological subtypes, and TP53 mutation status in UALCAN database. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001. KM: Kaplan–Meier; OS: Overall survival; PFS: Progression-free survival; RFS: Recurrence-free survival; DSS: Disease-specific survival; SLC6A13: Solute carrier family 6 member 13.
