As showed in Table 2, a strong correlation was discovered between increased expression of SNHG7 and poor OS in digestive system cancers (HR = 1.64, 95% CI =1.37-1.95, P < 0.000), other cancers (HR = 2.01, 95% CI = 1.57-2.57, P = 0.000). This evidence concerns the gene SNHG7 and digestive system cancer.
