Update to protocol of the Cochrane review of electronic cigarettes for smoking cessation (February 2025)

Amendment to protocol of the Cochrane review of electronic cigarettes for smoking cessation to remove the network meta-analysis (NMA) of our three primary outcomes: smoking cessation at six months follow‐up or longer; AEs at one‐week follow‐up or longer; and SAEs at one‐week follow‐up or longer. We will instead cite the more comprehensive network meta-analysis published in another Cochrane review from our group (10.1002/14651858.CD015226.pub2).
