Smoking Abstinence and Reduction Rates
smoking reduction
Smoking abstinence rates (CAR weeks 4-12), reduction rates (CRR weeks 4-12), and 7-day point prevalence of smoking abstinence and reduction are shown in Smoking abstinence rates and smoking reduction rates. CAR: continuous abstinence rate; CRR: continuous reduction rate; EC: electronic cigarette; HTP: heated tobacco product.Seven-day prevalence of smoking abstinence and reduction in the electronic cigarette (A) and heated tobacco product (B) study groups.High quit rates, evaluated on an intention-to-treat basis, were observed for both study groups; the CAR weeks 4-12 values for IQOS-HTP and JustFog-EC were 39.1% (43/110) and 30.8% (33/107), respectively (High reduction rates, assessed among participants who were still smoking, were also reported, and the CRR weeks 4-12 values for IQOS-HTP and JustFog-EC were 46.4% (51/110) and 39.3% (42/107), respectively (The 7-day point prevalence of smoking abstinence was >20% throughout the intervention phase, with values peaking at week 8 (V5) and week 12 (V6) (The 7-day point prevalence of smoking reduction (ie, dual use) was higher during the first 2 weeks of the intervention phase (For both study products,
