LINC00511 and cancer: Concerning the cut-off value subgroups analysis, whether the median was used as cut-off value (HR = 2.86; 95% CI: 2.43–3.38; p < 0.001; I2 = 0%; PH = 0.87) or the mean as cut-off value (HR = 2.24; 95% CI: 1.38–3.64; p = 0.001; I2 = 0%, PH = 0.99) or other cut-off values were used (HR = 2.80; 95% CI: 1.60–4.90; p < 0.001; I2 = 95.2%; PH < 0.001), high LINC00511 expression correlated with poor overall survival in cancer patients.
