This number of participants is for those who were current smokers when surveyed in the previous Wave (i.e., Wave 1), successfully followed up at the specified Wave (i.e., Wave 2), and with their quit attempt outcome being determined. “W2” means “Wave 2 of the survey”. This applies to other waves and numbers. For the full numbers of participants at each survey wave in each country please refer to Table 1. In some analyses the numbers of cases were fewer than the total, due to some “refused” and “missing” cases.
