Network diagram
As shown in figure 3, a network
diagram was conducted based on the six interventions (Baclofen,
Bupropion, Naltrexone, Topiramate, Varenicline, and Placebo). A total of
five direct comparisons and 10 indirect comparisons were included in
this diagram. Varenicline vs placebo occupied a larger proportion, and
the placebo group accounted for the largest sample size.
