Thus, the pooled HR was analyzed again after omitting ‘Zhang, R 2019’, and the result demonstrated that high expression of SNHG12 was still correlated to worse OS in different kinds of cancers (HR = 2.02, 95%CI 1.57–2.59, p < 0.00001, and I2 = 0.0%, p = 0.957, fixed model), indicating the stability and reliability of this meta-analysis. Here, SNHG12 is linked to cancer.
