Comparison of expression levels of reference genes and miRNAs detected in human saliva sample using RT-qPCR. Saliva samples were extracted using the Genomic DNA Extraction Kit, QIAamp DNA Mini Kit, and miRNeasy Tissue/Cells Advanced Micro Kit. Individual data points represent the Cq values of technical replicates, with horizontal bars indicating the mean. Statistical differences were determined at (P < 0.01)
