Hierarchical clustering of miRNA in sputum samples.

Abstract

<p>Samples were clustered according to the signature profile of 97 differentially expressed miRNAs. Data from each miRNA were median centered. Samples were in columns and miRNAs in rows. Red and green indicated high relative level and low relative level, respectively. The <i>P</i> values for these miRNAs were less than 0.05 in TB group compared with controls.</p
