Comparison of Oral Microbe Quantities from Tongue Samples and Subgingival Pockets

Table 5

Cross table for the detection (no/yes) of the microorganisms in tongue scrapings and subgingival samples. Additionally, percentages of agreement, Prevalence and Bias Adjusted Kappa (PABAK), specificities, and sensitivities are given.
