Objectives To analyze the cooperation and basic characteristics on systematic reviews/meta-analyses (SRs/MAs) in diagnostic test registered in PROSPERO platform, in order to provide reference for registering and preparing the SRs/MAs on diagnostic test.Methods We searched PROSPERO platform from inception to November 12th, 2017, to identify SRs/MAs on diagnostic test. Two reviewers independently screened records and extracted data by the inclusion and exclusion criteria. The forest figure was prepared by STATA 13.0 software. The figure of network of authors, organizations and countries were prepared by NetDraw software.Results A total of 240 SRs/MAs in diagnostic test were included. There was a serious imbalance in the quantity of the distribution of authors (1 050), organizations (360) and countries (34). These SRs/MAs in diagnostic test were related to 21 systematic diseases, with cancer ranking the first (52, 22%). Tissue biopsy was the most used gold standard, and imaging diagnosis was the most used diagnostic test. The most commonly retrieved English databases were PubMed, EMbase The Cochrane Library, while the Chinese databases were CNKI, WanFang Data and CBM. The search strategy were reported in 105 (43.8%) SRs/MAs on diagnostic test. The QUADAS-2 was used to assess the quality of included studies in 159 (66.3%) SRs/MAs in diagnostic test, and 105 (43.8%) SRs/MAs were supported by funding.Conclusions The absolute quantity of SRs/MAs in diagnostic test is still minimal. There are relationships among different authors, organizations and countries. The researcher should focus on the effective sizes and statistical methods in future.
