Smokers to receive nicotine patches

Reference no: EM13105819

Nicotine patches are often used to help smokers quit. Does giving medicine to fight depression also help? A randomized double blind experiment assigned 244 smokers to receive nicotine patches and another 245 to receive both a patch and the antidepressant drug bupropion. Results: After a year, 40 subjects in the nicotine patch group had abstained from smoking as had 87 in the patch-plus-drug group. Is this good evidence that adding bupropion increases the success rate? Carry out an appropriate test to help answer this question.
