lncRNA volcano plots and hierarchical clustering dendrogram of TB patients with distinctive TCM syndromes. a-c lncRNA volcano plots (fold change >2.0 and P < 0.05). The vertical lines correspond to 2.0-fold up and down (log2 ratio), and the horizontal line represents a P-value of 0.05. Each point in the plot represents a different transcript. Transcripts are isolated based on statistical significance and magnitude of change. Red squares represent significantly differentially expressed lncRNAs. d–f Hierarchical clustering dendrogram representing distinguishable lncRNA expression profiling of samples. PYD: pulmonary Yin deficiency syndrome; HFYD: hyperactivity of fire due to Yin deficiency syndrome; DQY: deficiency of Qi and Yin syndrome
