Figure 4. Clinical correlations between DE ncRNAs and hypertension. (A) Forest plot depicting logistic regression analysis results for the association between DE lncRNAs and circRNAs and general clinical data in hypertensive subjects. (B, C) Receiver operating characteristic (ROC) analysis of the relationship between LOC646616 and hsa_circ_0038648 expression and diagnosis of hypertension. (D) Heat map representation of a pairwise Spearman's correlation matrix for selected DE ncRNAs in hypertensive subjects (red and blue indicate positive and negative correlation, respectively; an r value of 1 or -1 indicates perfect correlation).
