However, S100A4 expression was not related to distant metastasis (Figure 3(b), RR = 1.23, 95% CI = 0.94–1.62, P = 0.13, random effects model) in 3 eligible studies or tumor histology (Figure 3(c), RR = 1.21, 95% CI = 0.99–1.47, P = 0.07, random effects model) in 7 eligible studies. Here, S100A4 is linked to neoplasm.
