Analysis of differentially expressed lncRNAs in TB patients and healthy controls. A The hierarchical clustering results depict the lncRNA expression profiles in the tuberculosis group and control group. “Red” indicates high relative expression, while “green” indicates low relative expression of lncRNAs. B The scatter plot illustrates the microarray data, with color representation for differentially expressed genes. The color “Red” corresponds to genes that are down-regulated by a factor of 2, while the color “Blue” corresponds to genes that are upregulated by a factor of 2. C The box plot is utilized to assess the distribution and dispersion of lncRNA data. After normalization, it was found that there was no significant difference in the distribution of the data
