Methods
Eight English and Chinese databases were searched for relevant RCTs published from their inception to May, 2015.We included eligible RCTs in which MT was employed either alone or as an adjuvant treatment for standard asthma medical therapy in children with asthma. Forced Vital Capacity (FVC), Forced Expiratory Flow in first second (FEV1) and FEV1/FVC were used as important outcomes in this research. The selection of studies, data extraction, and validation was performed independently by two reviewers. Cochrane risk of bias criteria was used for evaluating the quality of the included studies.
