Likewise, patients with advanced age (>40 years old) [OR = 0.23, 95% CI (0.05-0.92), pvalue = 0.038] presented with a significantly lower odds ratio for expressing high EGFR levels, whereas those with poor tumor grade [OR = 10.50, 95% CI (1.02-108.58); pvalue = 0.049] presented with significantly increased odds ratio for expressing high EGFR levels (Table 2). Here, EGFR is linked to neoplasm.
