Pooled results showed SPARCL1 expression was associated with differentiation (OR = 1.89, 95% CI: 1.38-2.59, p = 0.001), tumor stage (OR = 0.47, 95% CI: 0.29-0.77, p = 0.002), and distant metastasis (OR = 0.53, 95% CI: 0.33-0.84, p = 0.007) (Figures 4(a)–4(c)). This evidence concerns the gene SPARCL1 and neoplasm.
