Comment on: Effect of a nicotine-free inhalator as part of a smoking cessation programme: Table 1–

Abstract

The authors in their methodology described to be using the Fagerström Test for Nicotine Dependence (FTND), and it would be of interest also to know whether estimates with FTND as dependency parameter gave a similar result. Also, it would be of interest to know the actual duration of nicotine-free inhalator use in each of the two groups (median and range), and whether the concordance with the smoking cessation intervention (buproprion and high-dose nicotine patch) differed in the two groups, if these data are available.
