Pearson correlation score plot for saliva QC samples. This figure comprises four samples(mix01, mix02, mix03, mix04) arranged in a 2 × 2 grid. Each subplot displays pairwise correlations between technical replicates, with data points tightly clustered along the diagonal line (red) representing perfect correlation (y = x). The Pearson correlation coefficients (r) are annotated in the upper-right corners of each subplot, ranging from 0.9956 to 0.9966, indicating exceptionally high inter-sample agreement
