CRP and neoplasm: The male patients and high tumor stage were associated with elevated CRP levels (OR = 1.67, 95% CI: 1.34‐2.09; OR = 2.40, 95% CI: 1.44‐3.99; Figure 2A,B; Table 3), demonstrated by this meta‐analysis with low heterogeneity was low (I2 = 0.0%, p = 0.795; I2 = 64.3%, p = 0.038; Figure 2A,B; Table 3).
