A randomized controlled trial of telecare and face to face consultation with CA-F17 based on the standard smoking cessation program for nicotine dependence. - A randomized controlled trial of telecare and face to face consultation with CA-F17 based on the standard smoking cessation program for nicotine dependence.

We randomized 115 participants with nicotine dependence: 58 were allocated to the telemedicine (internet-based video counseling) arm and 57, to the control (standard face-to-face clinical visit) arm. We analyzed all 115 participants for the primary outcome. Both telemedicine and control groups had similar CARs from weeks 9 to 12 (81.0% vs 78.9%; absolute difference, 2.1%; 95% CI -12.8 to 17.0), and the lower limit of the difference between groups (-12.8%) was greater than the prespecified limit (-15%).
