Citational tracing of relevant databases adds few overlooked studies to a review.

Evidence

In a final step, we applied the ancestry approach in systematic reviews (Cooper, 1982; Mullen, 2003; Siess et al., 2014; Rockwood and Nathan-Roberts, 2018), which maps relevant publications that were referenced in these 73 publications. The ancestry approach only revealed seven additional (peer-reviewed) studies, bringing the total to 80. — Didier Caluwaerts et al., Deliberation and Polarization, 35
