  1. Note: The behaviour values are recorded as weekly behaviour frequency
  2. The t test results refer to the comparison between behaviour/automaticity levels at the point of the intervention and the end of the study. T0 values for vitamin C reflect pre-intervention levels, and T1 values for flossing reflect pre-intervention levels
