Table 10.

Descriptive statistics for percentage changes in PCR (ΔPCR%) from baseline V1 to V2, V3, and V4 differentiated by group (PP).

Group		Mean	SD	P25%	Median	P75%	Min	Max	Na
ΔPCR% (V2-V1)/V1	Control toothpaste	−30.1	47.2	−56.9	−36.4	−3.3	−100.0	176.0	85
	Test toothpaste	−22.6	59.1	−58.7	−25.0	1.9	−100.0	200.0	83
ΔPCR% (V3-V1)/V1	Control toothpaste	−32.2	58.2	−77.8	−38.9	0.0	−100.0	205.0	86
	Test toothpaste	−25.1	84.8	−72.7	−28.9	0.0	−100.0	575.0	82
ΔPCR% (V4-V1)/V1	Control toothpaste	−7.3	79.4	−60.9	−27.3	20.7	−100.0	314.3	86
	Test toothpaste	−13.7	104.6	−69.2	−32.5	7.1	−100.0	650.0	83

^adoes not sum up to 171 because in single subjects (n = 2 / n = 3) PCR was 0 at V1 and > 0 at V2, V3, or V4, respectively. If PCR was 0 at V1 and 0 at V2, V3, or V4, respectively, the corresponding ΔPCR% was set to 0.
