EGFL7 and neoplasm: Finally, although obvious differences in survival can be noted among tumor stages (stages 1, 2, 3 or 4, shown in Supplementary Fig. 2), the comparison of the curves (low EGFL7 expression vs. high EGFL7 expression) within each stage (stages 1, 2, 3 or 4) was not statistically different (P > 0.05).
