  1. Pairwise comparisons were tested from the omnibus linear mixed model. Test products in the same row that do not share superscripts significantly differ (p < 0.05) based on a linear mixed model. Additionally, mean values in bold indicate significantly a significant difference compared to UB cigarettes. The enough nicotine individual item is a component of the “relief” subscale. All items were answered on seven-point response scales from 1 (“not at all”) to 7 (“extremely”)
  2. UB usual brand; Min minimum; max maximum; VT Virginia Tobacco; and SD standard deviation
  3. N = 17–18 in each case
