When grouped according to the expression level of TUG1 in cancer patients, the pooled HRs for the increased TUG1 expression subgroup and decreased TUG1 expression subgroup were 1.91(95% CI: 1.33–2.75, P < 0.001)) and 0.63 (95% CI: 0.48–0.82, P = 0.001 with less heterogeneity), respectively. The gene discussed is TUG1; the disease is cancer.
