Background: Evidence on the effectiveness of the Epley manoeuvre in primary care is scarce.
Aim: To evaluate effectiveness at 1 week, 1 month, and 1 year of a single Epley manoeuvre versus a sham manoeuvre in primary care.
Design And Setting: Multicentre, double-blind randomised controlled trial in two primary care practices in Spain from November 2012 to January 2015.
Objective: The objective of the present review is to evaluate multicomponent/complex primary care (PC) interventions for their effectiveness in continuous smoking abstinence by adult smokers.
Design: A systematic review of randomised and non-randomised controlled trials was undertaken.
Eligibility Criteria For Included Studies: Selected studies met the following criteria: evaluated effects of a multicomponent/complex intervention (with 2 or more intervention components) in achieving at least 6-month abstinence in adult smokers who visited a PC, biochemical confirmation of abstinence, intention-to-treat analysis and results published in English/Spanish.
