The differences in the infiltration fraction of these 10 kinds of immune cells between the high and low OSGIN2 expression groups were shown in Fig. 5B. Spearman method was also used to list the correlation coefficients and p-value between the infiltration levels of the above 10 immune cells and OSGIN2 expression in GC, and significant associations were observed (Fig. 5C–L). Here, OSGIN2 is linked to gastric cancer.
