This 2021 umbrella review included five systematic reviews with a total of 212 randomised controlled trials and 237,760 participants. Fourteen intervention approaches were identified and classified into three categories: stand-alone web-based; stand-alone mobile phone-based and multicomponent interventions. Incorporating web and/or mobile-based interventions with face-to-face approach improved the rate of smoking cessation. However, there was no consistent evidence regarding the effectiveness of stand-alone Internet or mobile-based interventions. Further research is needed to evaluate stand-alone web-based and mobile phone-based interventions. |
