In the 19 empirical studies on TCKs from 2004 to 2020 which we were able to trace (Bikos et al, 2014;Bjørnsen, 2020;Désilets, 2016;Fanning & Burns, 2017;Gambhir & Rhein, 2019;Gilbert, 2008;Greenholtz & Kim, 2009;Kwon, 2019;Lijadi & Van Schalkwyk, 2014;Park, 2019;Moore & Barker, 2012;Murai, 2016;Poonoosamy, 2018;Purdon, 2018;Purnell & Hoban, 2014;Smith & Kearney, 2016;Walters & Auton-Cuff, 2009;Westropp, Cathro, & Everett, 2016) the following sample size information was found.
