Fig. 1

Hierarchical clustering plot (heatmap) of differentially expressed miRNAs in healthy controls (n = 5), healthy OSAHS (n = 5), OSAHS with arterial hypertension (n = 5). a Healthy OSAHS had dysregulated miRNAs compared to healthy controls (P < 0.05); (b) OSAHS with arterial hypertension had dysregulated miRNAs compared to healthy controls (P < 0.05); (c) 2 overlap miRNAs were up-regulated and the other 2 overlap miRNAs were down-regulated. The right bar represents the signal intensity of miRNA expression from − 2 (green) to 2 (red). Green: down-regulation; red: up-regulation; black: no change
