Comparison between CNVRs detected in the study with those in the previous reports.

Note: The comparison was based on Sscrofa 10.2 assembly (http://www.ensembl.org/Sus_scrofa/Info/Index). For CNVRs based on the other porcine assembly, we firstly converted the data to current genome coordinates using the UCSC LiftOver tool (http://genome.ucsc.edu/cgi-bin/hgLiftOver); CN loss counts were removed from our list while making comparison with Paudel et al., 2013 (22) as the study only reported copy number gain events.
