Besides, to explore the potential functions of these CNV-lncRNAs, we calculated the correlation of 34 CNV-lncRNAs with 19,513 protein-coding genes detected in osteosarcoma (significant correlation threshold set to ∣cor | >0.7 and P < 0.05) using the psych package in R. A total of 294 coding genes significantly associated with 10 CNV-lncRNAs (AL023806.1, TMEM78, C3orf36, CCDC140, C8orf86, FAM106A, CABIN1, PSMB1, CAPN15, and C10orf55) were screened (Supplementary Table 4), which were utilized to perform functional enrichment analysis (Supplementary Table 5). Here, CAPN15 is linked to osteosarcoma.
