RT Journal Article SR Electronic T1 Three year continuous abstinence in a smoking cessation study using the nicotine transdermal patch JF Heart JO Heart FD BMJ Publishing Group Ltd and British Cardiovascular Society SP 617 OP 618 DO 10.1136/hrt.78.6.617 VO 78 IS 6 A1 Robyn L Richmond A1 Linda Kehoe A1 Abilio Cesar de Almeida Neto YR 1997 UL http://heart.bmj.com/content/78/6/617.abstract AB A total of 305 subjects from Sydney were randomly allocated to receive either an active (24 hour transdermal nicotine patch over a 10 week course) or placebo nicotine patch. All subjects participated in a multicomponent cognitive–behavioural smoking cessation programme over five weeks in two-hour group sessions. The continuous abstinence rates at three years (validated by expired carbon monoxide) were 13.8% for the active group and 5.2% for placebo group (p = 0.011). The active nicotine patch with behavioural therapy achieved more than double the abstinence rates early in treatment compared with placebo and this difference was maintained throughout the three year follow up.
