In contrast, in Bai et al.’s [14] meta-analysis, the extracted data based on the survival curve (hazard ratio [HR] = 1.35, 95% confidence interval [CI]: 0.48–3.81) from Matsubara et al. [15] demonstrated that the expression of S100A4 was not associated with the prognosis of NSCLC. This evidence concerns the gene S100A4 and non-small cell lung carcinoma.
