Association between change in pack-years smoked or SmPEGS and change in smoking-associated damage to lungs and gums between ages 26 and 38 in the Dunedin Study. (a) and (c) show change in pack-years versus change in lung function and peridontal attachement loss, repectively. (b) and (d) show change in SmPEGS and change in lung function and periodontal attachment loss, respectively. The analysis is restricted to study members who smoked between ages 26 and 38 years
