Copy number profile of lncRNAs in osteosarcoma: (a) copy number of lncRNAs in osteosarcoma samples; (b) lncRNA copy loss and copy amplification proportion distribution in the genome; (c) the lncRNAs located in the focal CNA peaks are OS-related. False discovery rates (q values) and scores from GISTIC 2.0 for alterations (x-axis) are plotted against genome positions (y-axis); dotted lines indicate the centromeres. The amplifications and deletions of lncRNA genes are also shown. The green line represents 0.05 q value cut-off point that determines significance.
