Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Nicotine Patch, Experimental Use | Participants will continue to use nicotine patch after they lapse and resume smoking as long as smoking is less than 75% of pre study levels.~nicotine patch, experimental use: nicotine patch-transdermal, continue during lapses Nicotine patches are used according to normal package label, except if the participant lapses and smokes, they will continue to use the patch. | 1 | 356 | EG000 |
| Group 2 | Nicotine Patch, Labeled Use | Participants will discontinue using the nicotine patch when they resume smoking. This is the current FDA approved use of the nicotine patches.~nicotine patch, labeled use: nicotine patch-transdermal, discontinue during lapses Participants will use the nicotine patch while abstinent, but will remove the patch if there is a lapse and smoking resumes. This is the use indicated on current FDA approved labeling. | 1 | 345 | EG001 |
