Bioinformatics analysis of circRNAs expression patterns between group of obstructive sleep apnea (OSA) with acute myocardial infarction (AMI), OSA without AMI and healthy subjects using microarray technology. a Scatter plot with the mean expression values of each group samples. Raw junction reads for all samples were normalized by total mapped read numbers and were log.² transformed. b Heat map evaluation of the distinguishable circRNA expression patterns among the OSA with AMI, OSA without AMI, and healthy group. Each column represents one sample; each row represents one probe set; high and low expression was indicated by the “red” and “green” line, respectively. c The volcano graph was created to show significantly dysregulated circRNAs (fold change > 1.5, p-value < 0.05)
