FIGURE 3.

Time-dependency of qPCR-based Fusobacterium periodonticum cell count for each individual in the short-term (up to 1 month) dried saliva stains from 15 individuals. Sample duplicate set 1 is indicated in gray and sample duplicate set 2 in orange. Each dot represents a qPCR-run sample triplicate. R² values indicate the variation explained by the time since deposition in the bacterial cell count. Asterisks indicate the significance level of the Benjamini-Hochberg corrected p values as follows: 0.001 “***”, 0.01 “**”, and 0.05 “*”.
