Meanwhile, using a random‐effects model after 14 studies were pooled, our meta‐analysis also suggested that the HNSCC cases with high CRP levels performed worse in OS compared with those who carried a low CRP (HR = 1.48, 95% CI: 1.24‐1.77, I2 = 79.3%, p = 0.000; Figure 4D). Here, CRP is linked to head and neck squamous cell carcinoma.
