Comparison of the results from two different sample sets. (A) Scatter plot showing correlation of the 40 miRNA expression ratios (−ΔΔCq values) obtained from two different sample sets. Each dot represents the −ΔΔCq value of each miRNA that was obtained by comparison between healthy and periodontitis groups in sample set #1 (y‐axis) and sample set #2 (x‐axis). Spearman's correlation coefficient (ρ) = 0.95. (B) Box plot showing expression levels of 40 miRNAs indicated as −ΔCq. Red and green boxes represent the values of healthy and periodontitis samples, respectively. The results of different sample sets are presented separately. The upper panel shows the values of 19 up‐regulated miRNAs while the lower panel shows the values of 21 down‐regulated miRNAs. The central line in the box indicates the median, lower box bound the first quartile, and upper box bound the third quartile.
