Table 1 Calculation of fold_change values for lncRNAs and PCGs screened with Filter A

From: Integrated TCGA analysis implicates lncRNA CTB-193M12.5 as a prognostic factor in lung adenocarcinoma

  Cancerous sample Normal sample
Number of samples where expression is 0 A1 B1
Number of samples where expression is not 0 A2 B2
  1. fold_change = (A2 * (B1 + B2)/B2 * (A1 + A2)) > 2
