GROOVE (Graphical Representation of Overlap for OVErviews) is a methodological approach and a tool that facilitates the assessment of overlap of primary studies among multiple systematic reviews. This tool is intended to be used mainly by authors of overviews of systmatic reviews. The tool was made in Microsoft Excel, which we think could boost its wide usage. It has two versions: classical and heatmap.
The classic GROOVE tool has four sheets:
- The first sheet is an introductory sheet. It explains briefly what GROOVE is, how to use the tool and the optional advanced usage considering structural missingness.
- The second sheet is the only one that the user directly manipulates when entering data. It provides an empty matrix of evidence, supporting up to 70 systematic reviews and 1000 unique primary studies. The user must fill the systematic reviews IDs in the columns and the primary studies IDs in the rows.
- The third sheet is the GROOVE itself. It automatically provides the results of the overlap assessment, both overall and by pair of systematic reviews. It provides the results highlighting in colours the degree of overlap, according to previous recommendations (CCA 0-5% = slight; CCA 5-10% = moderate; CCA 10-15% = high; CCA>15% = very high)
- The fourth sheet is identical to the third, but it provides the results in greyscale colours.
The heatmap GROOVE tool is the same as the classical tool, but it provides the results as a heatmap in the third sheet.
