Objectives To systematically review the diagnostic value of GerdQ questionnaire for diagnosing the gastro-oesophageal reflux disease (GERD).Methods PubMed, Web of Science, EBMR, CNKI, CBM, VIP and WanFang Data databases were searched to collect studies on the diagnostic value the GerdQ questionnaire in diagnosing the GERD from inception to January 1st 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using Meta-Disc 1.4 software. We used the Stata 12.0 software to assess the publication bias with funnel plots.Results A total of 20 studies were enrolled, including 7 978 patients. Among them, 4 848 patients were confirmed with GERD. The results of meta-analysis showed that: a) The pooled sensitivity, specificity, +LR, −LR, and DOR were 0.79 (95%CI 0.78 to 0.81), 0.66 (95%CI 0.65 to 0.68), 2.28 (95%CI 1.77 to 2.94), 0.37 (95%CI 0.27 to 0.52) and 6.34 (95%CI 3.59, 11.19), SROC(AUC) was 0.789 3, and Q* was 0.726 6. b) When the cut-off was 7, the diagnostic accuracy of GerdQ questionnaire for the GERD was the highest, and that of 9 was the second. c) The diagnostic accuracy of GerdQ questionnaire was higher when it was used in China.Conclusions GerdQ questionnaire has a moderate accuracy for the diagnosis of GERD, which can be a useful complementary tool for diagnosing GERD, and can be popularized in clinical settings. Due to limitation of quantity and quality of included studies, the above conclusions requires verification by more high quality studies.
