  1. 1Cigarette D711 used a triacetin plasticiser; all other cigarettes used tri-ethyl citrate.
  2. 2Split-gap sizes changed with cigarette design.
  3. Lack of statistical difference at the 95% confidence level are denoted by * or Ç‚.
  4. Significance testing was not conducted for cigarette code D711 in comparison to D712, D721 or D732 as it‘s construction was slightly different to the other 21 mm cigarettes – it’s data are included for comparative purposes only. Significance testing was also not conducted on puff numbers as these are not discussed in the manuscript.
