We found that most studies did not report sources of support or conflicts of interest. Eight studies reported support from pharmaceutical companies (Cork 1995; Hammon 1984; Ivey 1983; Khuri 1987; Matangi 1989; Reves 1990; Serruys 2000; Vecht 1986), and nine studies reported departmental or other sources of funding, which we assumed to be independent (Booth 2004; Connolly 2003; Girard 1986; Gomes 1999; Harrison 1987; Rubin 1987; Sezai 2011; Sezai 2012; White 1984). One study declared support from both pharmaceutical and independent sources (Auer 2004). We would like to thank the authors involved in previous versions of the review (Danyel Azar, Martin Schillinger, Franz Wiesbauer), people who offered editorial support or advice in preparation of the protocol (M. M?llner, L. Richard, K. Schroeder and M.J. Zeitler), or editorial support in previous versions of the review (Jane Cracknell, Managing Editor; Harald Herkner, Content Editor; Cathal Walsh, Statistical Editor; Janet Wale, Consumer Editor). We thank peer review support in previous versions of the review (G. Guyatt, F. Botto, G. Lurati, M. Mrkobrada, P. Foex and J. Wetterslev), and assistance with translation of articles in Chinese (Y. Wang; formally of Linz General Hospital, Austria). We would like to thank Anna Lee (Content Editor), Susanne Schmitz (Statistical Editor), Ben Gibbison (Peer Reviewer), Janet Wale (Consumer Editor), Janne Vendt (Information Specialist), Jane Cracknell and Teo Quay (Managing Editors), and Andrew Smith (Co-ordinating Editor) for their help and editorial advice during the preparation of this systematic review.

N2 - The great popularity of geospatial data and increasing use in commercial as well as scientific applications is a significant event of our times. The overwhelming flow of data has made Database management systems (DBMS) a ubiquitous component for scientific research. However, although many database management systems have been built, there have been very few systematic comparisons of performance and functionalities especially few benchmark standards. In this paper, we aim to perform a performance evaluation for vector spatial databases and shows how the evaluation has been implemented in four spatial database systems, including object-relational database IBM DB2 Spatial Extender, Oracle Spatial, PostgreSQL and MySQL spatial. We expect this work to provide a standard benchmark in evaluating facilities and the efficiencies of various spatial database managers as well as guidance on selection for scientific application of spatial database.
