CD8A and cancer: Revisiting the results which are presented in Table 3, features CD8+CD45RA−CD27−CD28− (ID 4); CD4+CD45RA−CD27−CD28− (ID 9); CD4+CD45RA+CD27−CD28− (ID 10); CD3+CD56+CD8+CD4+ (ID 17) were among those flow cytometry features with the smallest IQR values (and, therefore, least variability in data) and which would potentially be good candidates for indicating the presence cancer.
