"Ce sujet a pour but d'étudier un sondage réalisé en 1972-1974 sur un panel de 1314 femmes n'ayant jamais fumé ou fumant actuellement (au moment du sondage). Ce sondage a été effectué afin d'éclairer des travaux portant sur l'impact du tabagisme sur des maladies thyroïdiennes et cardiaques (Tunbridge *et al.* 1977). Une suite de cette étude a été menée vingt ans plus tard (Vanderpump *et al.* 1995) afin de savoir si les personnes sont décédeés ou non. \n"

"Ce sujet a pour but d'étudier un sondage réalisé en 1972-1974 sur un panel de 1314 femmes n'ayant jamais fumé ou fumant actuellement (au moment du sondage). Ce sondage a été effectué afin d'éclairer des travaux portant sur l'impact du tabagisme sur des maladies thyroïdiennes et cardiaques (Tunbridge *et al.* 1977). Une suite de cette étude a été menée vingt ans plus tard (Vanderpump *et al.* 1995) afin de savoir si les personnes sont décédeés ou non. \n"
