*
As compared to UC, assuming UC effectiveness for SC of 8/100 and for RP of 5/28 and direct UC program costs of $4.85 per participant.
†
D, MI is dominated by UC (MI is more costly and less effective than UC).
‡
For infants of women who quit or remained abstinent—estimates are per participant in the target population.
LY, life-year; MI, motivational intervention; QALY, quality-adjusted life-year; RP, relapse prevention; SC, smoking cessation; UC, usual care; CS, cost saving.
