Randomized controlled trial of a computer-based, tailored intervention to increase smoking cessation counseling by primary care physicians.

Intervention patients were 1.77 (CI 0.94, 3.34, p = 0.078) times more likely than controls to be abstinent (12 versus 8%), a difference that approached, but did not reach statistical significance, and surpassed controls on number of days quit (18.4 versus 12.2, p < .05) but not on number of quit attempts.
