Kaplan-Meier analysis showing the overall survival of SGC patients categorized according to whether adjuvant therapy was provided or not. (A and B) Statistical significance of the difference between the curves of the patients showing high and low SPHK1 expression was compared in the non-adjuvant therapy (A) and adjuvant therapy (B) patient subgroups. (C and D) Statistical significance of the difference between the curves of the patients showing same SPHK1 expression was compared in the non-adjuvant therapy (C) and adjuvant therapy (D) patient subgroups. P values were calculated using the log-rank test.
