This conclusion comes from an updated Cochrane Systematic Review that considered the evidence of 48 trials that met stringent inclusion criteria.
"In updating the review we have distinguished between the different ways that telephone services were delivered and the differences in the participants," says lead Review Author Lindsay Stead, who works in the Department of Primary Health Care at Oxford University.
People who received repeated calls from a counsellor increase their odds of stopping by 50% compared to smokers who only receive self-help materials and/or receive brief counselling. Three or more calls seem to be particularly effective.
"Telephone quitlines provide an important route of access to support for smokers, and call-back counseling enhances their usefulness," says Stead.

2. The Cochrane Library contains high quality health care information, including Systematic Reviews from The Cochrane Collaboration. These Reviews bring together research on the effects of health care and are considered the gold standard for determining the relative effectiveness of different interventions. The Cochrane Collaboration (http://www.cochrane.org) is a UK registered international charity and the world's leading producer of systematic Reviews. It has been demonstrated that Cochrane Systematic Reviews are of comparable or better quality and are updated more often than the Reviews published in print journalsª.
