To determine a) the concordance among recent meta-analyses about which treatments for smoking cessation are vs are not efficacious, b) the similarity of odds ratios (ORs) across meta-analyses and c) among the validated treatments, the proportion of studies that found higher quit rates
Computerized literature search for meta-analyses in the last 5 yrs in PubMed and PsychInfo. Data were extracted from summary tables of overall effect of validated treatments
The 14 meta-analyses agreed 100% on the presence/absence of efficacy of 17 proven treatments. The ORs differed by < 0.5 in 72/76 of the comparisons of meta-analyses. Among the 37 meta-analyses that reported individual study results, in 33 meta-analyses, > 85% of the individual studies reported numerical superiority for the active treatment.
The efficacy of treatments for smoking cessation are extremely reliable. This argues for inclusion of treatment as an essential feature of tobacco control and clinical practice and argues for reimbursement of smoking cessation treatments on par with other medical and behavioral disorders.
