  1. The following lncRNAs were studied once and found statistically significant: LINC00968, LINC01234, LINC00476, FLG-AS1, HOTTIP, TC0101686, TC0100223. The following lncRNAs were studied once and were not found significant: linc-UBC1, KIAA0495, PART1, MGC21881, MIAT, PAR5, ADAMTS9-AS2, BCAR4, XLOC_010588, FOXCUT, 3 lncRNA risk score, FENDRR, HIF1A-AS2, ANRIL, GAPLINC, MRUL, HEIH, HOXA13, 48 lncRNA risk score, BANCR, ZXF1, CARLo-5, GAS6-AS1, Sox2ot, TUG1, NAG7 - LINC00312, CAI2, TC0101441, ENST00000480739, BC008363, 80-gene SChLAP1 signature risk score, 167-gene SChLAP1 signature risk score, CADM1-AS1, RCCRT1, CCAT1. Significance in the table refers to p-value < 0.05, as this is what had been used by these studies
  2. The ‘Times studied’ column refers to how many studies investigated each lncRNA. The ‘Number of cancer types’ column indicates in how many different cancer types each lncRNA was studied, with the total number of participants used to study each lncRNA in brackets. The ‘Median’ column indicates the median sample size for each cohort used to study each lncRNA, with the interquartile range (IQR) in brackets. The last column indicates how many times each lncRNA was found to be statistically significantly associated to prognosis and in brackets the relation of how many times it was found to be significant versus how many times it was studied
