The result suggests that high SLNCR1 expression was associated with poor OS (digestive system cancers: HR: 2.27, 95% CI: 1.62–3.17, I2 = 0%, P < 0.00001; nondigestive system cancers: HR: 1.78, 95% CI: 1.05–3.00, I2 = 0%, P=0.03) regardless of the subgroup (see combined HR data above). Here, LINC00511 is linked to digestive system cancer.
