Identification of EGFR as a Novel Key Gene in Clear Cell Renal Cell Carcinoma (ccRCC) through Bioinformatics Analysis and Meta-Analysis

Figure 15

Funnel plot for publication bias test between EGFR expression and ccRCC or progression. (a) Funnel plot for association between EGFR expression and ccRCC (cancer tissues versus normal tissues). (b) Funnel plot for EGFR expression in ccRCC with different Furhman grading (Furhman grading 1,2 versus Furhman grading 3,4). (c) Funnel plot for EGFR expression in ccRCC with different Pathological grading (T 1,2 versus T 3,4). (d) Funnel plot for EGFR expression in ccRCC with different lymph node status (LN- versus LN +). (e) Funnel plot for Forest plot for the association between EGFR expression and metastasis (M0 versus M1).
