10 different samples were used to analyze novel circRNAs. “Total read counts” contains overall chimeric reads (reads of all circRNA candidates ≥1); “Unique counts” represents total number of novel circRNA candidates; “DB” stands for circBase database; “% in DBs” equals the number of circRNAs in known DBs/circRNAs with canonical splice sites. In samples, T: Tumor; N: Normal; T – N: circRNAs present in tumor but not in normal tissues; N –T: circRNAs present in normal tissues but not in tumor tissues; N ∩ T: circRNAs present in both tumor and normal tissues.
