ObjectiveTo evaluate the methodological quality of systematic reviews and meta-analysis (SRs/MAs) in fields of integrated Chinese-western therapy for non-small cell lung cancer (NSCLC). MethodsSRs/MAs in fields of integrated Chinese-western therapy for NSCLC were searched inPubMed, EMbase, CBM, CNKI, VIP and WanFang Data from inception to July 10th, 2016. We also handsearched relevant journals such as Chin J Evid-based Med and reference of included studies, and tried to find the grey literature for additional studies. Two researchers independently screened literature and extracted data. Then methodological quality of included SRs/MAs were evaluated by AMSTAR scale. ResultsA total of 53 SRs/MAs were included, the highest and lowest scores of methodological quality were 9 and 1, respectively. The average score was 5.98±1.50. Results on the qualities of methodology or evaluation showed that 46 SRs/MAs (88.68%) was rated as moderate and 6 (11.32%) as low． The main problems were found in such areas as preliminary design scheme, literature searching, a list of included and excluded studies, etc.. ConclusionThe methodology of SRs/MAs in fields of integrated Chinese-western therapy for NSCLC have quality problems at different levels, further improvement should be expected.
